Federal airport screeners still find four to five guns at checkpoints on a typical day, the Transportation Security Administration's chief told a Senate hearing.

"Yesterday we found six, including one at ... Bradley (airport in Connecticut) -- a loaded gun with seven rounds in it, in a checked bag that (a passenger) was trying to get through," Administrator John Pistole said in a CNN report.

Passengers typically say they forgot the weapon was in their bag, the article said. But in one recent case, a passenger at Dallas-Fort Worth International Airport tried to board a plane with two pistols, three ammunition magazines, eight knives and a hand saw in a carry-on bag, the TSA said. That passenger was arrested by local law enforcement.

More than 900 guns have been recovered at checkpoints this year, the TSA says.
