US President Donald Trump has come to the defense of Defense Secretary Pete Hegseth, who is facing impeachment proceedings led by Republican Representative Thomas Massie over allegations of mishandling military operations, particularly the war in Iran. During an impromptu White House briefing on Monday, Trump labeled Massie a "loser" and criticized his attempt to impeach Hegseth as unfounded. Trump praised Hegseth for winning two wars, referring to successful military operations in Venezuela and Iran. The president's support for Hegseth comes amid growing criticism over the Pentagon chief's role in the administration's military operations, including the ongoing conflict with Iran and strikes on suspected drug-smuggling vessels in the Caribbean. Massie introduced eight articles of impeachment accusing Hegseth of abusing his powers and carrying out unlawful military actions, primarily concerning the Iran war but also referencing US operations in Yemen and Venezuela. The defense secretary has denied the allegations, describing the impeachment effort as a sham by "a disgruntled defeated congressman along with all his Democrat allies." The House is expected to vote on the impeachment resolution by mid-week, although its prospects remain uncertain due to reservations from Republican leaders about holding the vote during ongoing military operations. If the House impeaches Hegseth, the Senate would have to decide whether to dismiss the charges or hold a trial.
