The pardon also covers all lawmakers who served on the congressional select committee that investigated the Jan 6, 2021 storming of the Capitol by Trump supporters, and police officers who testified before it.

Trump, who will return to the presidency later today has repeatedly called for the prosecution of his perceived enemies since winning the White House in November.

Biden praised public servants as the “lifeblood of our democracy”. Without mentioning Trump, he expressed alarm that some of them were subjected to threats and intimidation for doing their job.

“These public servants have served our nation with honour and distinction and do not deserve to be the targets of unjustified and politically motivated prosecutions,” Biden said in a statement.

Trump in December backed a call for the FBI to investigate fellow Republican Liz Cheney over her role in leading Congress’s probe of the Jan 6, 2021, assault on the US Capitol by his supporters.

Fauci often clashed with Trump during the Covid-19 pandemic and his supporters have continued to attack the former senior health official.

Milley was quoted in the book “War” by Bob Woodward, which was published last month, calling Trump “fascist to the core” and Trump’s allies have targeted him for perceived disloyalty to the former president.

Reuters reported in November that the Trump transition team was drawing up a list of military officers seen as connected to Milley to be fired.
