Vice President Kamala Harris has been in touch with Emhoff since the evacuation and “he’s OK,” a White House official said.
District of Columbia Public Schools press secretary Enrique Gutierrez told reporters at the event that a bomb threat had been called into Dunbar High School in Northwest Washington, where Emhoff was holding an event.
“We had a threat today to the facility, so we did — basically we took the precaution of evacuating everybody, as you saw. I think everyone is safe. The building is clear. But I don’t have any specific details at this moment,” Gutierrez told reporters at the event.
A spokesperson for the Metropolitan Police Department confirmed to CNN that a bomb threat had been made. Later, the spokesperson told CNN the security threat was made by telephone and the investigation is ongoing.
The Secret Service said Tuesday that “there is no information to indicate” the threat was directed at Emhoff.
“This afternoon during an event attended by a Secret Service protectee, the Secret Service was made aware of a threat to the venue and immediately evacuated the protectee. At this time there is no information to indicate the threat was directed toward our protectee,” a Secret Service spokesperson said in a statement.
“In order to maintain operational security, the Secret Service does not discuss our protectees or the means and methods used to conduct our protective operations,” the spokesperson said.
Emhoff was visiting the school, located about two miles northeast of the White House, for a Black History Month event. He was scheduled to meet with school leaders, program directors and students participating in a program that helps them relate to history on a personal level.
As part of the program, which is done through a partnership with the National Parks Service students are provided opportunities to serve as docents and historical scholars on the life of Carter Woodson and local Black history, according to the White House.
Dunbar High School Principal Nadine Smith told reporters that the children at the school had been sent home for the day.
“Our protocol is to clear the building and move the kids away. DCPS just gave us directions to make sure, to go ahead and send the kids home. We won’t be able to clear the building for probably another hour or two,” Smith told the reporters.
As of late Tuesday afternoon, police had set up a perimeter around the school and two K-9 units were on scene. The DC Police Explosive Ordinance Disposal Unit is on the scene at the school, according to MPD spokesperson Kristen Metzger.
Multiple law enforcement officials familiar with the situation told CNN that the then-vice president elect remained inside the DNC for nearly two hours before the bomb was discovered.
