WASHINGTON — House Republicans are preparing to reject a Senate-passed funding bill to reopen most of the Department of Homeland Security, prolonging a more than 40-day shutdown. The impasse could mean more pain for hundreds of thousands of federal workers who are missing paychecks, and no permanent solution for long lines at airport security checkpoints. “It’s not going to pass as it is,” Rep. Chip Roy (R-Texas) told The Post less than an hour after former White House chief of staff Mark Meadows posted on X that the DHS bill was “dead in the House.”
