Trump revokes Biden, Kamala, Hillary's security clearances

US President Donald Trump made good Friday on a threat to revoke the security clearances of his predecessor Joe Biden and several senior former White House and national security officials.

The list of names stripped of their authorisation to see state secrets included Biden, his family members, and former vice-president and Trump presidential rival Kamala Harris.

Former secretary of state and defeated presidential candidate Hillary Clinton was on the list, along with Biden's secretary of state Antony Blinken and national security advisor Jacob Sullivan.

In a memorandum to agency heads and distributed by the White House communications office, Trump said the named officials should no longer be allowed access to classified material.

"I hereby direct every executive department and agency head ... to revoke any active security clearances held by the aforementioned individuals," Trump said.

"I also direct all executive department and agency heads to revoke unescorted access to secure United States Government facilities from these individuals."

Former US presidents and national security officials traditionally retain a security clearance as a courtesy, and some find it useful in seeking employment with private contractors.

But Trump, who continues to falsely claim that Biden schemed to steal the 2020 election, which he lost, has remained furious with his predecessor and lashes out frequently.
