"Transportation Security Officers in the four pilot airports are receiving very positive feedback from TSA Pre-Check travelers while the two partner airlines have successfully demonstrated the technical capabilities required to participate in the program, thus paving the way for other airlines to follow," Pistole said.
Pistole's testimony, as well as his appearance this week, come against the backdrop of TSA firing an employee for leaving a note with sexual implications in a passenger's baggage at Newark's Liberty International Airport last month.
Elsewhere, the House Transportation and Infrastructure Committee will hold a field hearing in Daytona Beach, Fla., about the Federal Aviation Administration's plans for its NextGen navigation system. The FAA plans for the NextGen system, which the agency envisions installing by 2020 at a cost of about $22 billion, to be installed to replace World War II-era radar technology in control towers by 2014 at the busiest airports, and nationwide by 2020.
Also this week, former President George W. Bush's Transportation Secretary Norman Mineta will deliver a speech in Washington about fuel economy standards for cars.
Mineta, who served in Bush's Cabinet until 2006 and before that as a Democratic member of California's House delegation, will speak Monday at the National Press Club. Mineta, who also was Commerce secretary under former President Clinton, will make the case for "technology neutral" clean-energy policies for automobiles.
