What to know about the Republican-led effort to impeach Pete Hegseth

Republican Representative Thomas Massie has introduced eight articles of impeachment against Defence Secretary Pete Hegseth, accusing him of misconduct including waging war without congressional authorisation. The effort could make Hegseth only the third Cabinet member in US history to be impeached, and would put lawmakers on record over his conduct and the Iran war.

The House is expected to hold a procedural vote on Tuesday evening, with impeachment votes possible as soon as Wednesday. Republicans have a narrow majority until January, so some joining Massie and Democrats could be enough to pass the measure; Senate conviction appears less likely. Hegseth called the effort a “political spectacle”, while President Donald Trump publicly praised his response. The article also links the eight-month Iran war to concerns about prolonged conflict and fuel costs.
