Republican Mike Johnson narrowly won re-election as House speaker, overcoming hard-right GOP opposition with support from President-elect Donald Trump. The tense atmosphere highlighted challenges ahead for Johnson, who promised to cut government size and scope. Despite Trump's backing, the close vote revealed his precarious position. House Democratic leader Hakeem Jefferies called for unity, while the Senate has already elected its leaders. Trump's endorsement of Johnson was pivotal, but the situation echoes past difficulties in electing a speaker.
