The Pentagon on Monday said that it was reviewing what it called “serious allegations of misconduct against” Sen. Mark Kelly of Arizona, who was among six Democratic lawmakers harshly criticized by President Donald Trump for urging members of the military to refuse to follow unlawful orders.

The Defense Department did not detail the claims against Kelly, who is a retired captain in the U.S. Navy. The department also did not say who made the allegations.

But in a statement revealing the probe on X, the Pentagon suggested that the investigation relates to Kelly’s comments about the power of service members to refuse to follow illegal orders.

The Pentagon said that a “thorough review of these allegations has been initiated to determine further actions, which may include recall to active duty for court-martial proceedings or administrative measures.”
