The government shutdown is starting to affect air travel. All TSA employees and air traffic controllers are essential but unpaid. That means they don't have money for bills, mortgages, child care, etc. If the shutdown continues, they have to find other work that pays. TSA workers in particular, are not even paid the standard government employee rates so it's not likely they have piles of savings sitting around drawing interest.

No TSA inspectors? No airline flights. Trump will have shut down the entire industry! Which means most Congressmen can't travel. Most businessmen can't travel. The airlines operate on a thin margin so they are that close to bankruptcy. Trump has crippled the nation. That's when Senate Republicans start threatening McConnell with loss of leadership if he won't let them vote on the CR.
