A man with a rifle opened fire on Republican lawmakers at a congressional baseball practice Wednesday near Washington, wounding House GOP Whip Steve Scalise of Louisiana and several others as congressmen and aides dove for cover. The assailant fought a gun battle with police before being shot and killed.

A congressional aide and a volunteer also were wounded, along with two U.S. Capitol police officers.

A look at previous security incidents at the Capitol or political violence involving members of Congress:

— March 29, 2017: A 20-year-old woman described as “erratic and aggressive” drives a vehicle into a Capitol Police cruiser and is taken into custody, closing down streets near the Capitol for nearly three hours. Shots were fired during the arrest attempt, but the event appeared to be criminal in nature with “no nexus to terrorism,” Capitol Police said. No one was injured.

— March 28, 2016: Police shoot a man after he pulled a weapon at a Capitol checkpoint as spring tourists thronged Washington. Congress was not in session. Police identified the man as 66-year-old Larry Dawson of Tennessee, who was charged with assault with a deadly weapon and assault on a police officer while armed.

— Jan. 14, 2015: A 22-year-old Ohio man is arrested by the FBI in an alleged plot to attack the Capitol in support of the Islamic State terror group. Christopher Lee Cornell of suburban Cincinnati pleaded guilty to three charges, including attempted murder of U.S. officials and employees. Court documents show Cornell said he wanted to attack during President Barack Obama’s State of the Union address.

A federal judge ruled Hoyt was insane at the time of the offense.

— Oct. 3, 2013: Miriam Carey, a 34-year-old dental hygienist from Connecticut, is shot and killed by Capitol Police officers in her vehicle outside the Hart Senate Office Building.

Her family later filed a wrongful-death lawsuit against the Secret Service and Capitol Police.

Weston was then wounded and captured.
