US President Donald Trump has revoked security clearances from his previously defeated Democratic election rivals, Kamala Harris and Hillary Clinton, as well as a number of other top former officials.

The move comes after Trump said in February he was revoking security clearance for his predecessor Joe Biden.

He confirmed that move in the latest announcement, adding that he was also revoking the security clearance of "any other member" of the Biden family.

"I have determined that it is no longer in the national interest for the following individuals to access classified information," Trump's memorandum read.

Former US presidents and top security officials usually keep their security clearance as a courtesy.

Former Secretary of State Antony Blinken and former Republican lawmakers Liz Cheney and Adam Kinzinger were also on the list of those who lost their security clearances - as well as Fiona Hill, a former Russian affairs adviser in the first Trump administration.

The other names were: Jake Sullivan, Lisa Monaco, Mark Zaid, Norman Eisen, Letitia James, Alvin Bragg, Andrew Weissmann and Alexander Vindman.

Trump had earlier pulled security clearances of more than four dozen former intelligence officials whom he accused of meddling in the 2020 election in Biden's favour without providing evidence.

In 2021, Biden - serving president at the time - barred his defeated rival Trump from having access to intelligence briefings citing his "erratic behaviour".
