TUCSON, Ariz. (13 News) - Sen. Mark Kelly said Monday he will not be intimidated by President Donald Trump after the Pentagon announced it is investigating the Democratic lawmaker for allegedly breaching military law.

Kelly hosted a news conference responding to the investigation, which stems from a video he participated in with five other Democratic lawmakers, urging troops to disobey unlawful orders.

One week ago, Pentagon officials announced they are investigating Kelly. Defense Secretary Pete Hegseth said Kelly faces investigation because he is a formally retired Navy captain still under Pentagon jurisdiction.
