Bar handed over the position to Trump before resigning last month, sources said.
White House officials are also considering how the federal investigation into the uprising affects other pardons being discussed by Trump, such as his personal lawyer, Rudy Gilliani, who called for a “trial”
“The situation in DC has raised problems in the White House even over pardons,” said a man close to the White House.
Additional pardons are expected from the White House before Trump leaves office next week.
CNN did not receive an immediate response from the White House, and Barr did not immediately comment to CNN.
However, the note said that the incumbent president could resign and then be pardoned by his vice president once that person takes office. This happened when President Gerald Ford pardoned Richard Nixon in 1974.
Two separate sources close to Vice President Mike Pence say Pence is unlikely to pardon Trump in this scenario. Pence was a loyal supporter of the president, but now feels frustrated and disappointed with Trump for his behavior around the uprising and did not call to check on him during and after the riots, many sources said.
Trump can still be pardoned, even if his administration disapproves. Self-forgiveness would extend only to federal crimes, not protect Trump from state action, including an investigation by New York prosecutors into Trump’s personal and corporate finances.
The White House office will usually ask the Legal Council Office of the Ministry of Justice to give an opinion on important legal issues. This office is responsible for giving opinions on the power of the executive branch and is generally inclined to broaden the perspective of the presidential branch.
Trump’s opposition to Bar and Tsipollon to forgive is remarkable, as they are both staunch defenders of Trump, with an expansive executive during Russia’s investigation and impeachment proceedings in 2020 at his urging with the Ukrainian president.
Recently, both men have been at odds with the president over his campaign lies. Bar left office in December after publicly saying there was no widespread election fraud, and Tsipollone is considering resigning in recent weeks after strongly disagreeing with the president and his desire to use his cabinet to repeal election results.
