Suspect killed after opening fire on Secret Service checkpoint outside White House, officials say

WASHINGTON, D.C. (WINK) — A suspect was killed after opening fire on a Secret Service checkpoint outside the White House Saturday evening, a Secret Service spokesperson told CBS News in a statement.

Secret Service officers returned fire, hitting the suspect, who was taken to a hospital, where he died. A bystander was also wounded during the incident, but no Secret Service agents were injured.

President Trump was at the White House during the incident, "but was not impacted," the Secret Service spokesperson said. 

Two other sources told CBS News that a suspect opened fire on a security booth where U.S. Secret Service officers were stationed inside, and officers returned fire. The sources said the suspect and a bystander were wounded, but no agents were injured. 

Approximately 20 shots were heard just after 6 p.m. Eastern Time. They appeared to be coming from the side of the White House complex containing the Eisenhower Executive Office Building, the reporters said. 

Secret Service spokesperson Anthony Guglielmi said in a statement to CBS News that the agency was aware of "reports of shots fired near 17th Street and Pennsylvania Avenue NW" and is "working to corroborate the information with personnel on the ground." 

FBI Director Kash Patel said in a social media post that the FBI was "on scene and supporting the Secret Service."

CBS News White House associate producer Emma Nicholson said a CBS News crew was preparing to record for "CBS Weekend News" when they heard the shots and "ducked to the ground." Nicholson said they were then ushered into the White House "shortly after."

The security concern comes nearly a month after a gunman breached the security checkpoint outside the Washington, D.C., hotel ballroom where the White House Correspondents' Dinner was taking place.
