Four House Democrats who took part in a video reminding military personnel not to obey illegal orders said the F.B.I. had requested to interview them. In a statement, the lawmakers accused President Trump, who previously called the video seditious behavior punishable by death, of using the nation's top law enforcement agency to “intimidate and harass members of Congress.” On Monday, the Pentagon announced it was investigating Senator Mark Kelly of Arizona, a retired Navy captain and astronaut, over the video.
