The Pentagon on Monday said it is reviewing "serious allegations of misconduct" against US Democratic Senator Mark Kelly.
Kelly, a retired US Navy captain, was one of six Democratic lawmakers who recently urged service members to refuse unlawful orders.
The announcement in a post on the Department of War X account did not detail the allegations against Kelly, but suggested the move is in response to Kelly's statements: "All servicemembers are reminded that they have a legal obligation under the UCMJ to obey lawful orders and that orders are presumed to be lawful."
Kelly said he learned of the investigation via the Pentagon's social media post on Monday.
"If this is meant to intimidate me and other members of Congress from doing our jobs and holding this administration accountable, it won't work," Kelly wrote on X.
