U.S. President Donald Trump has canceled Secret Service protection for former vice president and 2024 Democratic rival Kamala Harris, a senior White House official said on Friday (August 29).

Former vice presidents typically receive six months of Secret Service protection after they leave office.

Harris' protection was extended to one year, until January 2026, by then-President Joe Biden before he left office last January, the official said.

Harris is to embark in September on a 15-city book tour for her memoir, "107 Days," about her unsuccessful presidential run. She was the Democratic nominee for 107 days after Biden withdrew from the race in the weeks following a disastrous debate against Trump. Trump went on to defeat Harris.

The letter to Harris, dated Thursday, says the termination of additional security is effective September 1, the official said.

Kirsten Allen, a senior adviser to Harris, said in response to the decision: "The vice president is grateful to the United States Secret Service for their professionalism, dedication, and unwavering commitment to safety," she said.
