A new government report won't help the troubled Transportation Security Agency win any new fans.
Since 2007, the TSA has spent nearly $1 billion to train agents how to identify and screen suspicious passengers.
But the Government Accountability Office calls the program, known as SPOT, a waste and essentially says it has been "ineffective."
According to the report, TSA failed to apply lessons learned from 20,000 covert tests at 450 commercial airports. But the agency says it has upgraded its screening practices based on test results.
The report, the subject of a hearing on Capitol Hill Thursday, also shows the results of profiling were probably "no better than chance."
Republicans and Democrats are considering defunding the program.
