PROBLEM: (CNN)  -- A Utah man trapped for more than 26 hours in a crevice of a popular cave tourist attraction died as rescuers struggled to save him, authorities said Thursday. John Edward Jones, 26, of Stansbury Park was stuck in the Nutty Putty Cave, which sits west of Utah Lake near Cedar Valley, according to the sheriff's office of Utah County. The cave is 55 to 60 miles south of Salt Lake City. Sheriff's officials said Jones entered the cave at around 6 p.m. Tuesday with a group of about 11 people and became stuck about 8:45 p.m. in a "tightly confined" feature inside Nutty Putty Cave called "Bob's Push." Utah County sheriff's spokesman Sgt. Spencer Cannon told CNN affiliate KSL that Jones was trapped upside down in a crevice that was about 18 inches wide and about 10 inches high. The crevice is about 150 feet below the surface and about 700 feet from the cave entrance, according to the sheriff's department. "They had him to a level spot where he wasn't heading downhill with his head below his feet," Cannon said. "During the course of that, they have a raising system to hold him in position, and one of the devices of that system failed, and Mr. Jones actually fell back to the area where he had been stuck for so long." Shortly before midnight on Wednesday, rescuers got close enough to Jones to conclude that he was not breathing and he had no pulse. Rescue officials were meeting Thursday to determine how to recover Jones' body. Rescuers had tried to reach Jones for more than 24 hours, but had problems navigating the treacherous terrain, Cannon said. "Getting people to him is very difficult," Cannon told KSL before Jones died. "It is a tightly confined space. When there is movement, it is literally millimeters at a time." There are narrow areas of the cave where visitors have to crawl on their bellies to get through, according to the attraction's Web site. Up to 5,000 people visit each year, the site said.

PROBLEM: Washington (CNN) -- New details emerged of what the White House knew about the Internal Revenue Service targeting of conservative groups, with spokesman Jay Carney disclosing Chief of Staff Denis McDonough was among the top officials made aware of the matter late last month. In a new timeline provided by Carney to reporters on Monday, General Counsel Kathryn Ruemmler learned on April 24 of a pending Treasury inspector general's report on how IRS staff used criteria targeting conservative groups in assessing eligibility for tax-exempt status. According to Carney, Ruemmler told McDonough as well as other Treasury officials about the pending report. It was the first time the White House acknowledged that McDonough was aware of the report before it became public in early May. IRS: By the numbers . In addition, Carney made clear that the information Ruemmler received on April 24 included details of improper acts by IRS officials. At the same time, Carney emphasized that the information was preliminary and could have changed before the inspector general released his final report on May 14. Carney insisted no one -- including Ruemmler and McDonough -- told President Barack Obama anything about the inspector general's pending report before media reports about it began appearing on May 10. "We knew the subject of the investigation and we knew the nature of some of the potential findings, but we did not have a copy of the draft report," Carney said. "We did not know the details, the scope, or the motivation surrounding the misconduct and we did not know who was responsible. Most importantly, the report was not final and still very much subject to change." Opinion: What happened to Obama's promise? However, the new information on Monday continued a perception of a White House on the defensive over the issue, one of at least three controversies dogging Obama as his second term reaches the four-month mark. The Senate Finance Committee will hold the second congressional hearing on the matter Tuesday, after the House Ways and Means Committee grilled the outgoing acting commissioner of the IRS last Friday. On Monday, the Senate panel's Democratic chairman and ranking Republican sent a letter to the IRS official, Steven Miller, seeking an exhaustive list of information about the case. Another hearing is set for Wednesday by a third panel -- the House Oversight Committee. Some Republicans are calling for a special investigation into the IRS matter, in which tax officers assessing applications for tax-exempt status used key words such as "tea party" in determining levels of scrutiny. CNN Poll: Likability helps Obama survive brutal week . Separately on Monday, a Northern California tea party group filed the first lawsuit against the U.S. government stemming from the IRS targeting. "The IRS and its agents singled out groups like NorCal Tea Party Patriots for intensive and intrusive scrutiny, probing their members' associates, speech, activities and beliefs," according to the suit filed in Cincinnati. "NorCal and its members suffered years of delay and expense while awaiting the exemption and spending valuable time and money answering the IRS' questions. The result was a muffling and muzzling of free expression" the lawsuit claimed. The group alleged violations under the Privacy Act as well as violations of its constitutional rights guaranteeing free expression and equal protection under the law. Opinion: We're pointing a gun at our democracy . Carney offered the new timeline in response to the first question at his daily media briefing, when a reporter noted "confusion" over what Ruemmler was told about the inspector general report in late April. He noted the report found no outside intervention in the IRS targeting of what he called "inappropriate scrutinizing of conservative groups" seeking tax-exempt status, and that no one in the White House intervened in the inspector general's review or "did anything that could be see as intervening." In addition, Carney said, the misconduct had stopped in May 2012, almost a year before Ruemmler or anyone else at the White House were told of it by anyone at Treasury. At the same time, Carney disclosed that White House and Treasury officials discussed the pending inspector general's report in the weeks before its formal release, even though he said no one told Obama about it. The White House first was notified of the upcoming report, known as an audit, on April 16, he said, calling that a routine notification also provided to Congress. Ruemmler was told about it eight days later and she informed McDonough and others about it shortly thereafter, Carney said. "Ruemmler was informed that the inspector general for tax administration was completing a report about line IRS employees improperly scrutinizing what are known 501(c)(4) organizations by using words such as 'tea party' and 'patriot'," he said. In particular, Carney said that "at no time did anyone on the White House staff intervene with the IRS inspector general audit." "There were communications between the White House Counsel's office and White House Chief of Staff's office with Treasury Office of General Counsel and Treasury's Chief of Staff office to understand the anticipated timing of the release of the report and potential findings by the" inspector general, he said, but added that Ruemmler acted properly in not informing the president. IRS official denies intentional political targeting, lying to Congress . "The cardinal rule, as I said, is you do not intervene in an independent investigation and you do not do anything that would be, that would give such an appearance particularly when the final conclusions, as was the case here, have not been reached," Carney said. "That is the doctrine we followed and the bottom line is, and this isn't just the most important fact, it is what we have said from the beginning - neither the White House nor Treasury intervened in the inspector general's audit." Last week, Miller blamed a huge increase in workload, rather than deliberate targeting, for "foolish mistakes" in the political discrimination cited by the inspector general's report. He told the House Ways and Means Committee that the IRS division handling requests for tax exempt status was overwhelmed by a surge that followed the Supreme Court's 2010 Citizens United decision. "I think that what happened here was that foolish mistakes were made by people who were trying to be more efficient in their workload selection," Miller said, calling the practices described in the inspector general's report as "intolerable" and a "mistake," but "not an act of partisanship." He apologized for what he later called "horrible customer service," but he also stubbornly rejected any accusation that it amounted to politicizing the work of the IRS. However, Republicans noted the increased requests for tax exempt status didn't kick in until 2011, months after the targeting began, according to the inspector general's report. Rep. Dave Camp, chairman of the Republican-led panel, and other GOP members sought to depict the controversy as indicative of government gone wild, with the IRS abusing conservative groups and other political foes of the administration. Democrats on the committee also expressed outrage at the targeting of conservative groups seeking tax-exempt status, but they pointed out that the top IRS official at the time was appointed by Republican President George W. Bush, not Obama. Opinion: IRS scandal is about donors, not tax . They also noted that the inspector general's report stated there was no evidence of any political motivation for what happened, or influence from outside the IRS. The Treasury Department oversees the quasi-independent IRS. Some Republicans are trying to find a link between the Obama administration and the IRS targeting. According to the inspector general's report, the IRS developed and followed a faulty policy to determine whether the applicants were engaged in political activities, which would disqualify the groups from receiving tax-exempt status. The controversial move began in early 2010 and continued for more than 18 months, the report said, declaring that "the IRS used inappropriate criteria that identified for review Tea Party and other organizations applying for tax-exempt status based upon their names or policy positions instead of indications of potential political campaign intervention." Among the criteria used by IRS officials to flag applications was a "Be On the Look Out" list, which was discontinued in 2012, the report said. Conservative groups complain their requests were delayed for months or even years through the targeting that sought to prevent ineligible political groups from getting tax exempt status. Miller testified Friday that determining the political nature of groups was one of the hardest tasks of IRS officers tasked with assessing requests for tax exempt status. The investigation by the Treasury inspector general for tax administration was initiated after congressional complaints began to surface in the media in 2012 that the IRS was targeting conservative groups and holding up applications. In a written response included in the report, the IRS commissioner of the Tax Exempt and Government Entities Division said there was no criminal behavior behind the actions of the agents, but rather inefficient management. Obama called the inspector general's findings outrageous and forced Miller's resignation. In addition, the commissioner of the IRS' Tax Exempt and Government Entities Division also announced his retirement Thursday. Joseph Grant will leave in June, according to an internal IRS memo provided to CNN. Miller also is scheduled to exit then. Obama has appointed Danny Werfel, a White House budget office official who has served in both Democratic and Republican administrations, to succeed Miller through the end of the fiscal year on September 30.

PROBLEM: (CNN) -- Travel warnings from the U.S. Department of State didn't stop Faith Hentschel, 65, from venturing to Iran this May to visit the rustic sites in ancient Persepolis and the colorful bazaars in Tehran. A photo of Khaju Bridge in Isfahan, Iran, taken by an American traveler. "I had no idea what to expect," said Hentschel, who spent two weeks in Iran after booking the trip through a private tour operator and applying for a visa. "I was stunned with the friendliness of all the Iranian people. That alone makes me want to go back." Iran is still a relatively rare destination for Americans, creating a niche market for only a handful of tour operators across the nation that organize group trips for travelers once or twice a year. And with news of the arrest of three American backpackers, along with the June election riots and government crackdown, Iran may be an even harder sell, some travel companies said. "It really depends on the political climate and the perception of Iran," said Mike McDonnell, who operates the site BestIranTravel.com in San Francisco, California. The site books trips for non-Iranian travelers interested in visiting. His site saw a decline in booking travel to Iran this summer. "It's already really hard to get to Iran in the first place." Officials at the U.S. Department of State say travel warnings have been implemented on Iran since the hostage crisis in 1979, when militants captured 52 American diplomats and staff. The Americans were held for 444 days. Since then, the two countries have had no diplomatic relations. U.S. passports are valid for travel to Iran and visas are required to enter the country, according to the State Department Web site. Going with an organized tour group is the easiest way to attain a visa. Travelers who do visit Iran run the risk of being denied entry, U.S. officials say. In some cases, Iranian officials have prevented American citizens, academics, scientists and journalists from leaving the country, and even detained, interrogated and imprisoned some on unknown or various charges, the Web site said. "It's made well-known that the destination [Iran] could be perilous for American citizens," said Darby Holladay, spokesman at the State Department. Last week, three Americans were detained after crossing into northern Iran during a hiking trip. The two men and one woman, said to be seasoned travelers, began their trip in Turkey and went into Iraq before crossing the unmarked border into Iran. The U.S. State Department and the Australian and British government warn against traveling into the border zones. "Obviously, we are concerned," Secretary of State Hillary Clinton said Monday to reporters. "We want this matter brought to a resolution as soon as possible." Mudhafer Mohammed, owner of the Miwan Hotel, told CNN that the hikers said they had come to the area because they heard it was safe. Mohammed said he tried to discourage them from going to Ahmed Awa, a popular tourist destination in the northern Kurdish region of Iraq. "I told them, 'Don't go there because it is unsafe for you because you're American and Ahmed Awa is very close to the Iranian border,' " Mohammed told CNN. It is unclear whether the three wandered into Iran accidentally or intentionally entered the country. Pauline Frommer, creator of the Pauline Frommer's Travel Guides, said it's  safer when visiting countries in conflict to use travel companies and tour operators that rely on local accommodations and guides. She warned against staying in big hotel chains, which have been targets in recent terrorist attacks in Indonesia and India. "When it's an iffy destination, it's always a good idea to try and travel under the radar," she said. "You don't want to be a target." Despite worries about safety, demand for visiting Iran has grown in recent years. Last May, travel writer Rick Steves shot a 10-day video of his visit to Iran in a one-hour special that launched on PBS. The project cleared up misconceptions about Iran and sparked Americans' interest in traveling there, travel experts said. At Geographic Expeditions, a luxury travel company that organizes trips to Iran, the number of participants doubled from 25 in 2007 to 50 in 2008. Spiekermann Travel Service, Inc., one of the oldest travel agencies that specializes in Iranian travel, has booked more than 350 tours to the country since it began operating there in 1995. "My path is known," said Ihab Zaki, owner of Spiekermann, which is based in Michigan. He said he began offering tours after he visited the country himself and was awed by its history and art. "We send all our paperwork to local governments and they know we are coming. I don't let my people roam around in the middle of nowhere. It's very safe." But the recent uncertainty in Iran has caused interest to wane. Spiekermann's bi-annual trips to Iran, limited to 14 travelers, usually sell out. But only four have signed up for the fall trip. Far Horizons Archaeological & Cultural Trips, Inc. in San Anselmo, California planned a second trip to Iran for October after their first trip in May sold out. But owner Mary Dell Lucas said the trip maybe be canceled because travelers are withdrawing. "What's happening most recently is scaring people," she said. "Those three Americans made a mistake, but with us, it's very different. We are taking a group, and we are invited." Lucas' firm and other tour companies say they take precautions.  Participants are required to abide by Iranian law, which means women must dress conservatively and cover their heads with scarves. A professor and a local guide, who are familiar with the country, accompany the American travelers. Barbara Bailey, a 73-year-old from rural Ohio, went on a two-week vacation to Iran last April with a tour group. Her favorite part of the trip was talking to the Iranian women at the local restaurants. "I went because nobody has really been before, and I know they have a wonderful history," Bailey said. "If you can get past the government, the people there are great." If travelers can't afford to spend between $6,000 and $10,000 on organized excursions of  two or three weeks and decide to backpack, they still need to follow the rules, said Jon Dorn, editor in chief of Backpackers Magazine. "If you're going to a place that's not like America, then do your homework on what's appropriate," said Dorn. Backpackers Magazine, an online and print publication specializing in backpacking, hiking and travel, reaches 2.5 million readers in the U.S. Dave Stevenson, who oversees the Web site www.travel-security-and-safety.com, said hikers should be equipped with GPS systems, satellite or cell phones and maps when traveling in border areas, especially in conflict zones. They should also notify relatives back home where they are hiking abroad. "The world is a big place," Stevenson said, "And there are always plenty of places to hike that aren't dangerous or war zones." CNN's Arwa Damon contributed to this report.
