"Mike Johnson’s disastrous handling of the continuing resolution unquestionably left his future speakership imperiled with several members rethinking whether they can back him in January," one House Republican was quoted as saying by the news portal on Monday.
Johnson's fate largely depends on whether US President-elect Donald Trump will continue to support him, the report noted.
"There’s nothing Mike Johnson can do between now and the Speaker’s race to regain the trust of Republicans in Congress. He’s as lame of a duck as Joe Biden," another Republican lawmaker added.
On Monday, the Semafor news portal reported that Trump's allies accuse Johnson of betraying Republican interests after Congress passed a bill to finance the government. Johnson introduced the bill that did not contain Trump's key demand - raising the debt ceiling before the president-elect's inauguration.
