Example Input: (CNN) -- Responding to an allegation by the U.S. chairman of the Joint Chiefs of Staff that Pakistan's main intelligence agency has a "longstanding relationship" with a Taliban-allied insurgent group that targets U.S. troops in Afghanistan, a senior Pakistani intelligence official said: "We do have a relationship: that of an adversary." "We have made our resolve very clear that (the Haqqani Network) is an enemy we need to fight together," said the official, who did not want to be identified discussing intelligence matters. In an interview that aired Wednesday on Pakistan's Geo TV, Adm. Michael Mullen spoke forcefully about the Haqqani Network, which he said "very specifically facilitates and supports the Taliban who move in Afghanistan, and they're killing Americans." "I can't accept that and I will do everything I possibly can to prevent that specifically," he said. Then Mullen said Pakistan's Inter-Services Intelligence "has a longstanding relationship with the Haqqani Network. That doesn't mean everybody in the ISI, but it's there." "I also have an understanding that the ISI and the (Pakistani military) exist to protect their own citizens, and there's a way they have done that for a long period of time," Mullen said. "I believe that over time, that's got to change." Based in Pakistan's North Waziristan frontier, the Haqqani Network "has been at the forefront of insurgent activity in Afghanistan, responsible for many high-profile attacks," according to the United Nations. The group is believed to have three main sources of funds: donations from the Persian Gulf region, drug trafficking, and al Qaeda payments. Pakistani forces in December announced they had seized Nasiruddin Haqqani, son of the group's leader, Jalaluddin Haqqani. Other U.S. officials in recent months had expressed concerns that Pakistan has not been aggressively confronting militants operating in the tribal regions. The Pakistani intelligence official told CNN that "we have our hands full" fighting other Islamist militant groups along the border with Afghanistan, notably those under the umbrella of the Lashkar-e-Tayyiba (LeT)  "and once we are through with them we can turn on the other (the Haqqanis). We do not have the capacity to undertake simultaneous operations." The official said the "onus of providing proof of this" relationship was on the Americans and it was not up to the ISI "to start providing clarification." Asked if offense was taken by Mullen's remarks, the intelligence official said: "Not personally, no." Earlier in the Geo TV interview, Mullen was pressed on issues such as the arrest of CIA contractor Raymond Davis and unmanned drone strikes against targets within Pakistan, which have marked what he called a "rough patch" of increasingly complex relations between the two nations in recent months. The admiral traced the difficulties back to the 12-year period in which the two countries had severed diplomatic ties, then restored them in the midst of the global terrorism crisis that followed the attacks of September 11, 2001. "We can't snap our fingers and say all of the sudden we trust each other," he said, "and that's what we're trying to work our way through in the midst of these huge terrorist challenges that we both have." "It's the focus from the United States' perspective on the terrorist threat (in the Federally Administered Tribal Areas), the al Qaeda leadership which still lives there and still threatens to kill as many Americans as they possibly could, combined with what I would call this federation of terrorist organizations that are getting along more than they used to, and at least from my experience ... the complexity is increasing, not decreasing." As Joint Chiefs chairman, Mullen is the highest-ranking uniformed official in the U.S. military's chain of command. He has been part of recent discussions that have included CIA Director Leon Panetta and their Pakistani counterparts: Chief of Army Staff Gen. Ashfaq Parvez Kayani and the ISI's director, Lt. Gen. Ahmad Shuja Pasha. Mullen's term is set to end this year. "It's been a very rough patch lately," Mullen said, "and I think the leaders, including Generals Pasha and Kayani, Director Panetta and myself and others are very committed to working our way through this because we see the need to solve this problem, and we just can't walk away from it." CNN's Nick Paton Walsh, Zarifmo Aslamshoyeva and Nasir Habib contributed to this report.

Example Input: Washington (CNN) -- If the threat of underwear bombs became known last Christmas, why did airport screeners only recently begin aggressively checking for them? The answer is two-fold, Transportation Security Administration Director John Pistole told reporters Tuesday. First, the lack of a permanent leader at the TSA hindered change, he said. Secondly, the agency needed time to train screeners on the new pat-down protocols. The threat of hidden bombs became instantly clear on December 25, 2009, Pistole said, when authorities arrested Umar Farouk AbdulMutallab, a Nigerian man, after his failed attempt to ignite his hidden explosive on a flight from Amsterdam to Detroit, Michigan. TSA officials immediately started looking at what they needed to do to modify technology or pat downs to detect the bombs, he said. But at that time, the top job at TSA was filled by a career official. The White House delayed nominating a TSA chief and then White House and Congressional Republicans feuded for a year over nominees. Much of the debate centered on whether the nominees supported unionization of airport screeners. Two of President Obama's nominees withdrew from consideration. "Frankly it just came down to the fact there was not a presidentially appointed, Senate-confirmed administrator in place until I was confirmed at the end of June to make a really significant decision like that, that would have impact on a number of people," Pistole said. "That was a big part of it." Pistole was sworn in as administrator in July and soon thereafter made the decision to go through "enhanced pat downs." Training time accounts for the rest of the delay, as the TSA quietly began pilot programs in Boston, Massachusetts, and Las Vegas, Nevada, in August, and rolled the program out nationwide in early November. Pistole consistently has said it was his decision to implement enhanced pat downs. He said he opted not to publicize them in advance because he felt to do so would be to give a "roadmap" to would-be terrorists. Implementation of the pat downs was further delayed because time was needed to train screeners on the new protocols, he said. Those protocols are considered sensitive security information, and have not been shared with the public. But Pistole said protocols do not allow for screeners to grope passengers. Pistole said some passenger descriptions of the procedures are "so wildly outside the standard operating protocols that it just absolutely should not be happening. If it is, then we'll take appropriate action." "If we receive any complaints from a passenger about something happening, then we immediately follow up both with that passenger and with our security officers," he said. Most airport checkpoints have closed circuit television systems, which help investigators find out what happened, he said. Videotape helped dispel one passenger's complaint that she was handcuffed to a chair and mistreated, he said. "If there's a security officer that did something that's not appropriate, then we take appropriate action. I just want to make sure that I have all the facts," Pistole said.
Example Output: The failed underwear bombing last Christmas raised the threat of bombs hidden in clothes .
Pistole says after that, the pat-down program was delayed by two factors .
The TSA lacked a permanent leader until July .
Extensive training also was required before implementation of the program, he says .

Example Input: (CNN) -- Parts of the Eastern United States on Friday fended off freezing rain and snow as a powerful winter storm lumbered through the Great Lakes, driving thunderstorms eastward. The National Weather Service predicted the storm would affect the Upper Midwest, Great Lakes and the Northeast, with blizzard conditions in Minnesota and Iowa and strong winds across a portion of the Great Lakes and Ohio Valley. Severe storms -- with wind and large hail -- were possible from Boston to Miami, said CNN meteorologist Sherri Pugh. Frozen conditions may have been a factor in a crash early Friday in Maine that left a driver dead. An SUV driver lost control of the vehicle while it was traveling on a snow-covered stretch in Somerville and slammed into a big rig, the Lincoln County Sheriff's Office said. Several New York-area airports -- LaGuardia, Kennedy and Newark in northern New Jersey -- were experiencing ground delays as of 6 p.m, due to limited visibility, the Federal Aviation Administration reported online. The wild weather also brought strong winds to parts of the Southeast and mid-Atlantic, though that threat was over by evening. Before then, the weather service reported two possible tornadoes early Friday afternoon in south-central Georgia, including one in Johnson County that damaged 12 buildings, including ripping the front doors off a fire station. There was also an EF0 tornado -- indicating 65 to 85 mph winds lasting three seconds or more -- in Compton, Maryland, 60 miles southeast of Washington, D.C. Heavy winds also downed trees in Kentucky, North Carolina, South Carolina and Virginia, while up to quarter-size hail was reported on Florida's Atlantic coast around St. Augustine. This all came on the heels of severe storms that struck Illinois late Thursday afternoon, knocking out power, damaging buildings and spawning floods, the National Weather Service reported. On Thursday night, storms and high winds swept across Tennessee, pelting Nashville with rain and hail and leaving thousands in the dark. In Illinois, damaging wind and golf ball-size hail were reported overnight. About 24,000 people in the state lost power, according to utility Ameren Illinois. Effingham and Champaign counties in Illinois reported flooding. "We have some power lines down and a little water in the road in some places," said Pam Jacobs, director of the Effingham County Emergency Management Agency. John Dwyer, emergency management coordinator for Champaign County, reported road flooding and standing water in farm fields. He said the flooding was caused by 3 inches of rain Thursday coupled with the snow melt. The National Weather Service said radar indicated rainfall of 3 to 4 inches per hour. The Illinois State Police reported that fog caused a wreck on Interstate 57 in northeast Illinois, involving at least 27 vehicles. Authorities said they received reports of injuries, none of them life-threatening. As the storm moved eastward, winds knocked down dozens of trees in Nashville, reported CNN affiliate WSMV-TV. The station said trained weather spotters reported 1-inch hail and 95-mph winds. CNN's Ed Payne, Greg Botelho and Ralph Ellis contributed to this report.
