Republican Thomas Massie seeks to force House vote on impeaching Defense Secretary Pete Hegseth over Iran war

Republican lawmaker Thomas Massie, an outspoken critic of President Donald Trump, introduced eight articles of impeachment against US Defense Secretary Pete Hegseth on Monday as pressure builds on the Trump administration over the Iran war.

The resolution proposed by the Kentucky congressman accuses Hegseth of conducting the war illegally without congressional authorization. Massie also claims Hegseth has abused his powers as the head of the Pentagon.

Massie is using a special procedure that could see the US House of Representatives vote on the resolution within two days, with the legislative chamber still dominated by Republicans.

What will Democrats do with their midterm mandate?

Earlier on Monday, Hegseth sought to downplay rumors about the push against him.

"My team, we’re not worried about the noise," he told reporters.
