Person Arrested with a Weapon at Joint Base Andrews After Vice President Harris Arrives

(CNN) — Security personnel at Joint Base Andrews in Maryland arrested one person with a gun Sunday night, while another remains at large, according to a news release, shortly after Vice President Kamala Harris arrived at the base.

Security personnel deployed barriers to stop the intruders’ vehicle, which arrived around 9 pm ET and did not follow orders at the base’s main gate, according to the statement. There were no shots.

Harris had arrived at the base at 8:47 pm ET aboard Air Force Two, the group reported, after a trip to Selma, Alabama, to commemorate the 57th anniversary of Bloody Sunday.

The motive behind the incident was not immediately clear.

Both the Vice President and Second Gentleman Doug Emhoff were in the Marine Two helicopter around 8:51 p.m. ET, according to a press report, and had left the base according to a group report around 9 p.m. Harris’ office told the group that his staff and Transportation Secretary Pete Buttigieg; the Secretary of Education, Miguel Cardona; Housing and Urban Development Secretary Marcia Fudge and Environmental Protection Agency Administrator Michael Regan, who were traveling with Harris, had safely left the base, according to a news report at nearly 10 pm.

President Joe Biden flew directly back to the White House aboard Marine One helicopter after spending the weekend in Wilmington, Delaware.

Television reporters traveling with Biden landed separately at Joint Base Andrews and saw people searching a wooded area with flashlights and several speeding police cars.

The group of journalists traveling with Biden was safely outside the base by almost 10 pm ET. The group of journalists who traveled with Harris was also off the base at 11:55 pm ET.

CNN has reached out to the US Secret Service for comment.
