Reporter stopped by TSA agent who didn't know D.C. was in the U.S.A.

ORLANDO, FL -- A Washington D.C. based reporter had trouble getting through airport security, because one TSA agent had no knowledge about the District of Columbia's existence. 

According to Reporter Justin Gray, a TSA agent didn't recognize his District of Columbia driver's license as valid identification at the Orlando International Airport. Gray says he asked the TSA agent, \"Do you not know what the District of Columbia is?\" Gray reports it was clear the agent didn't.

The TSA says their agents will be trained on how to identify valid documents including District of Columbia driver's licenses. 

. @TSA Agent in Orlando never heard of \"District of Columbia.\" Demanded passport because he didn't believe my drivers license was from US!?
