WASHINGTON (AP) — New House Speaker Mike Johnson is facing his first big test as he tries to win House Republican support for a short-term funding plan to avert a government shutdown. The task looks increasingly difficult. Federal agencies are making plans for a shutdown that would shutter government services and halt paychecks for millions of federal workers and military troops. It’s a disruption that Johnson has said he wants to avoid. But House lawmakers left Washington without a plan after a week of setbacks. Republicans who were granted anonymity to discuss internal deliberations say Johnson is still sounding out support among Republicans and is expected to unveil the legislation over the weekend.
