The largest flight attendants union in the United States has blasted President Donald Trump‘s effort to deploy Immigration and Customs Enforcement officers at airports, calling it an “invasion” and urging the government to pay Transportation Security Administration officers instead.

“Flight Attendants will not allow the TSA and the frontline Transportation Security Officers (TSOs) who keep us safe to be used as pawns in this dangerous game, nor will we fly in an aviation system that doesn’t put our safety and security first,” the Association of Flight Attendants-CWA (AFA) said in a statement on Sunday. “This latest threat of ICE invasion at the airports is another distraction from solutions that protect Americans.”
