The deranged CalTech grad who allegedly opened fire during the White House Correspondents’ Dinner has been indicted for trying to kill President Trump, court papers show.

Cole Allen was hit with four felony counts: attempt to assassinate the President of the United States, assaulting an officer of the United States with a deadly weapon, transportation of a firearm and discharging a firearm during a crime of violence.

He faces up to life in prison if convicted on the top charge.

Allen is accused of trying to get through a security checkpoint, armed with two guns and knives, one floor above where the political soirée was underway and where President Trump, wife Melania and most of Trump’s top cabinet were in attendance on April 25.

Allen opened fire and hit one secret service agent who was saved by a bullet proof vest, the feds said.

He was arrested at the scene and the dinner was evacuated.

Allen, a Torrance, Calif., native, has yet to enter a plea.

During a court hearing Monday, a judge apologized to him for the fact he’d been kept in extremely restrictive conditions in jail on suicide watch, after hie lawyers argued he didn’t pose a physical threat to himself.
