House speaker Mike Johnson faces crucial Friday vote as support in doubt

The embattled Republican can only afford to lose one vote as GOP prepares to elect its congressional leader

Mike Johnson's grip on the House speakership faces a crucial test on Friday, as mounting opposition from within his own Republican party threatens to derail his re-election bid, despite receiving an endorsement from President-elect Donald Trump.

With Republicans holding a razor-thin 219-215 majority in the House, Johnson can only afford to lose one vote - a threshold already reached after the Kentucky representative Thomas Massie publicly declared his intention to vote against the incumbent speaker.
