(CNN) -- Authorities found four human bodies abandoned in the Arizona desert Thursday. Initial indications point to exposure as the probable cause of death, said Victor Brabble, a spokesman for U.S. Customs and Border Protection. "It is probable that they are immigrants attempting to cross into the U.S.," he said. "However, we don't have enough to draw a conclusion on it now." The bodies were found near Gila Bend, Arizona, about 70 miles north of the border. They have not been identified, the Maricopa County Sheriff's Office said. Immigrants often try to cross the Sonoran Desert's harsh terrain, and there are many heat-related deaths, Brabble said Thursday. Immigrant rights advocates have warned that even as border crossings decrease, deaths are on the rise as increased border security forces people to choose more dangerous crossing routes. Border patrol officials have argued that more security is necessary to stop smugglers. According to a recent study by the Binational Migration Institute at the University of Arizona, more than 2,230 migrants have died in the state's desert area along the border in the past 22 years. In the border region of Pima County, Arizona, deaths of unidentified migrants in the desert have become so common the Medical Examiner's Office has helped create a website to track the deaths and assist family members searching for their loved ones' remains. On Thursday, a bipartisan group of senators announced a proposal to add 20,000 more border agents, complete 700 miles of fence along the boundary with Mexico, and deploy $3.2 billion in technology upgrades similar to equipment used by U.S. forces in Iraq and Afghanistan. The proposed amendment, negotiated by a group of senators from both parties known as the "Gang of Eight," is intended to ensure Senate passage of a major immigration reform bill with enough Republican support to persuade the GOP-controlled House to also take up the measure. Journalist Valeria Fernandez and CNN's Tom Cohen, Dana Bash and Ted Barrett contributed to this report.

LONGMONT, Colorado (CNN) -- A Colorado solar-energy company has high hopes for the economic stimulus bill that President Barack Obama will sign Tuesday in Denver. AVA Solar CEO Pascal Noronha holds one of the solar panels his company produces. Obama touts that the stimulus bill will help create up to a half a million so-called "green" jobs in the field of alternative energy. Colorado has a growing green energy industry. Executives of AVA Solar, based in Fort Collins, Colorado, are among green energy industry representatives invited to the bill signing. AVA Solar has its plant in Longmont, about 30 minutes north of Denver. The plant, set to begin production in the spring, will construct solar panels for solar power plants. Once production is up to speed, CEO Pascal Noronha says, the plant should create enough solar panels a year to power 40,000 U.S. homes. Noronha says AVA Solar needs two things: Government loans to expand its factory, and more government assistance to help power companies commit to building large solar power plants in the United States. iReport.com: What would you fix first? Noronha says those two moves would help AVA Solar create 1,000 to 2,000 new jobs in its factory, plus added employment for its suppliers. The company, founded in 2007, currently has 175 employees. Without the stimulus, Noronha said, AVA Solar is on track to create 420 new jobs by the end of this year. AVA Solar currently operates on $175 million in U.S.-based private venture capital. In 2007 the company also received $3 million in seed money from the U.S. Department of Energy. Noronha says Obama is on the right track in terms of the stimulus bill. "What everybody needs is a little seed money because five years from now there's no question [that] solar has to replace the oil that we import," Noronha says. "What the government needs to do is provide the traction that is needed to get the first few projects on the ground." "We need money from the federal government ... to facilitate production immediately," the CEO adds. "Otherwise, we will be sitting and waiting for projects in the U.S., and if we have to wait one year or two years -- when we're able to produce a solution for this country today -- that is a really good reason for the government to say, 'Here it is, let's go.' " Noronha says his company's biggest customer base is in Germany, a country that is far ahead of the United States in embracing solar energy. Obtaining U.S. customers is a priority, he explains. "As a company we would very much like to have customers here in the U.S.," Noronha says. "The government needs to be able to facilitate these customers by making it possible for them to put large-scale power plants up." Noronha is optimistic about the stimulus bill and the direction of the Obama administration. "If you look at the vision of the president, you know he is looking out in the future and saying we've got to reduce our dependence on foreign oil," Noronha says. "Well, to reduce our dependence on foreign oil, there is only renewable energy. And there are two forms that are promising -- one is wind and the other is solar. And solar, you've got the sun's resources all over the world."

LOS ANGELES, California (CNN) -- The Transportation Security Administration said Friday its officers at a Texas  airport appear to have properly followed procedures when they allegedly forced a woman to remove her nipple rings -- one with pliers -- but acknowledged the procedures should be changed. The woman involved -- Mandi Hamlin -- told reporters earlier Friday she was humiliated by last month's incident, in which she was forced to painfully remove the piercings behind a curtain as she heard snickers from male TSA officers nearby. The incident occurred at the Lubbock, Texas, airport. The officers "rightly insisted that the alarm that was raised be resolved," the TSA said in a statement posted on its Web site Friday afternoon. "TSA supports the thoroughness of the officers involved as they were acting to protect the passengers and crews of the flights departing Lubbock that day." However, "TSA has reviewed the procedures themselves and agrees that they need to be changed," the statement said. "In the future, TSA will inform passengers that they have the option to resolve the alarm through a visual inspection of the article in lieu of removing the item in question." Hamlin and her lawyer, celebrity attorney Gloria Allred, said they want a public apology from the agency, as well as a guarantee that future passengers with piercings will be treated with dignity and respect. Allred pointed out that TSA's Web site says passengers with piercings can undergo a pat-down inspection if they do not want to take their piercings out -- an option she said Hamlin was never offered. "The conduct of TSA was cruel and unnecessary," Allred told reporters at a news conference. "Last time that I checked, a nipple was not a dangerous weapon." She said if an apology was not forthcoming, "Mandi is going to have to consider her legal options." Attempts by CNN to reach Allred for a response to the TSA statement Friday afternoon were unsuccessful. TSA said in its statement it acknowledges "that our procedures caused difficulty for the passenger involved and regrets (the) situation in which she found herself. We appreciate her raising awareness on this issue and we are changing the procedures to ensure that this does not happen again." The incident occurred February 24 as Hamlin, 37, was preparing to fly to Dallas-Fort Worth from Lubbock, where she had been visiting her elderly great-uncle. Hamlin said she also has navel and ear piercings and has never set off a metal detector or been singled out for additional screening at an airport. She did not set off the metal detector at Lubbock International Airport, but was pulled to the side for additional screening, Allred said. A hand wand used by a TSA officer beeped when it was waved over her breasts. Hamlin told the officer she had nipple piercings, Allred said, and that officer called over another officer, who told her she would need to remove them. "Ms. Hamlin did not want to remove her nipple piercings," Allred said, reading from a letter she sent TSA. "After nipple rings are inserted, the skin can often heal around the piercing and the rings can be extremely difficult and painful to remove. In addition, once removed, the pierced skin may close up almost immediately, making it difficult and painful to reinsert the piercing." More officers were called over, and the group grew to four male and two female TSA officers, according to Hamlin. Also, a small crowd of onlookers had started to gather. The officers insisted that Hamlin remove the nipple rings, Allred said. "She felt humiliated by the scene that the TSA officers were making," Allred said. "With tears streaming down her face, she again asked to show the piercings to a TSA officer instead of having to remove them. She was told, however, she would not be allowed to fly unless she removed them. Had she been told that she had a right to a pat-down, she would have chosen that option." She eventually was taken to a private area behind a curtain to remove the piercings, Allred said. One came out easily, but the other would not, and she called to an officer that she was having trouble and would need pliers. She was handed a large pair, Allred said. "As Ms. Hamlin struggled to remove the piercing, behind the curtain she could hear a growing number of predominately male TSA officers snickering in the background," Allred said in the letter. "Mandi Hamlin was publicly humiliated. ... Clearly, this is not how passengers should be treated."  Watch the passenger demonstrate removing the jewelry » . Afterward, Hamlin underwent another scan, but realized she had forgotten to remove her navel ring. She offered to remove it, Allred said, but an officer told her it was not necessary because he could see it. Hamlin wondered why a similar visual inspection of her nipple rings would not have sufficed, Allred said. "I wouldn't wish this experience upon anyone," Hamlin told reporters. "I felt surprised, embarrassed, humiliated and scared. No one deserves to go through this." In a statement earlier Friday, the TSA said it "is well aware of terrorists' interest in hiding dangerous items in sensitive areas of the body. Therefore, we have a duty to the American public to resolve any alarm that we discover." TSA included in its statement a picture of a prototype training device it will use to simulate a "bra bomb" in training and testing its officers. Hamlin said she had to visit the person who originally pierced her nipples to get the rings reinserted, and said the process was excruciatingly painful because of the scar tissue that had formed. "People who are pierced should not be snickered at, should not become the object of ridicule, should not be singled out for special and uneven and unequal treatment," Allred said. "They should be respected just like everybody else." She said she had received a call from TSA's public affairs office Friday morning. "We hope that means they're going to jump on this and do something about it," she said. "We want TSA to do the right thing now. We're going to give them the opportunity." Hamlin said she will continue to fly but will avoid the Lubbock airport. The next time she visits her great-uncle, she said, "I will be driving." E-mail to a friend .
