Sen. Mark Kelly, D-Ariz., is being investigated by the Pentagon over “serious allegations of misconduct,” the Department of Defense announced Monday, launching the inquiry after Kelly, a military veteran, appeared in a controversial video alongside other Democratic lawmakers urging military troops to refuse illegal orders.

The investigation comes after Kelly, who served as a captain in the Navy and participated in Operation Desert Storm, appeared in a video that told military members they can and must refuse illegal orders, accusing the Trump administration of pitting the military against American citizens as it looks to deploy the National Guard to multiple cities.

The Pentagon said a “thorough review” has been launched into Kelly, noting the probe may recall the senator to active duty for a court-martial.
