From NPR.

The alleged gunman at the White House Correspondents’ Dinner, where President Trump and other top administration officials were gathered, is set to make his first appearance in court today.

Cole Allen, 31, is slated to be arraigned in federal court. Police have not formally identified Allen as the suspect, but NPR confirmed his identity with two people familiar with the investigation who aren’t authorized to speak publicly.

Before the shooting, Allen allegedly sent his family members what the White House is calling a manifesto, stating he wanted to target members of the Trump administration, a White House official told NPR.

That official also said Allen’s sister had spoken with law enforcement, telling them her brother had a tendency to make radical statements and had alluded to a plan to do "something" to fix the world’s problems.

Allen faces charges including using a firearm during a crime of violence and assault on a federal officer using a dangerous weapon, according to U.S. Attorney for the District of Columbia Jeanine Pirro.
