Transportation Security Administration officers continue to be confused about their nation’s capitol.

District of Columbia Del. Eleanor Holmes Norton sent a letter Tuesday to TSA Administrator David Pekoske Wednesday about a Washington, D.C. resident who had issues at the Newark International Airport with her driver’s license.

Holmes Norton said that a TSA officer denied that the I.D. was valid and had to consult with colleagues before allowing the D.C. resident to catch her flight.

“As I am sure you can imagine, it can be humiliating for a U.S. citizen to be delayed because a federal government does not recognize the name of the District of Columbia,” Del. Holmes Norton wrote in her letter.

A Washington journalist tweeted in 2014 that a TSA agent in Orlando “never heard of ‘District of Columbia.’ Demanded passport because he didn’t believe my drivers license was from US!?”

D.C. officials replaced “Washington D.C.” with “the District of Columbia” in 2014, which Del. Holmes Norton credited with the TSA’s troubles. This year, officials decided to return to the “Washington D.C.” labeling.

A local Fox affiliate reported in July that Minneapolis TSA officers had a 95 failure rate during an internal test in which undercover agents smuggled explosive materials, fake weapons and drugs through screening.
