President Donald Trump has cancelled Secret Service protection which had been arranged for Kamala Harris by Joe Biden before he left office, according to one of her advisers.
As a former vice-president, Ms Harris was entitled under law to receive six months of this extra security after leaving office in January.
Her protection had been extended for another year by an executive directive signed by her former boss but this was revoked by Trump in a memo, seen by the BBC, which is dated Thursday.
The BBC has asked the White House and the Secret Service for comment.
The move comes just weeks before Harris embarks on a national book tour to promote "107 Days" - a memoir of her short-lived and ultimately unsuccessful presidential campaign in 2024.
