Air traffic controller Jack Criss, a single father, says he's had to make difficult financial decisions to support his family during the government shutdown.

Air traffic controller Jack Criss is now clearing takeoffs and takeout orders. The single dad took on a side gig as a DoorDash delivery driver during the second-longest government shutdown in modern history in order to make some extra cash and cover his daughter’s high school tuition.

For the past few weeks, air traffic controllers have been receiving partial pay – but next week, they’re expected to miss their first full paychecks as the funding lapse continues.

“It’s been incredibly difficult. You can feel the tension, and it’s heavy…and it hurts,” Criss said in an interview that aired on “CBS Saturday Mornings.”

As the government shutdown rolls into Day 25, Congress remains unable to strike a deal. The Senate failed to advance measuresThursday that would pay federal employees like Criss.
