PITTSBURGH (AP) — Transportation Security Administration workers are venting frustration with the current government shutdown at a rally inside the Pittsburgh airport.

The rally, organized by union leaders representing the 450 TSA workers in Pennsylvania, got underway Friday morning at the Pittsburgh International Airport’s ticketing level.

Union President William Reese says TSA employees in Pittsburgh and elsewhere are worried about feeding their families and paying bills. He says “morale is at an all-time low.”

Democratic U.S. Rep. Conor Lamb is speaking at the rally, calling on his colleagues in Congress to end the shutdown.

TSA agents at other airports around the country are also planning rallies for Friday.

The partial government shutdown has reached its 28th day.
