WASHINGTON D.C- The T-S-A wants to make sure the busiest travel time of the year doesn't get even busier.

"Hello, I"m TSA Adminstrator John Pistole," Pistole says in a new public service announcement. He's asking passengers at airports nationwide to support tougher new security measures. "We very much appreciate your involvement, cooperation and assistance in ensuring the safety of the travelling public" he goes on to say in the PSA.

Pistole's message comes amid backlash over the government's use of full body scanners and pat-downs some say are too aggressive. Kevin Haymes is one of the hundreds of passengers to complain. He says of his pat down, "at one point the agent had his hands actually on the top of my pants and I was taken aback by that."

Homeland Security Janet Napolitano defends the stepped up measures. Napolitano says, "we hope that people will understand the goal, the purpose for what is being done."

Protestors are calling for a national opt-out today tomorrow. Asking flyers to skip the body scans and force the enhanced pat down. The experts say if even a few people do it dozens of airports could experience huge delays.
