Biden has raised concerns that investigations would further divide a country he is trying to unite and risk making every day of his presidency about Trump, said the sources, who spoke on background to offer details of private conversations.

They said he has specifically told advisers that he is wary of federal tax investigations of Trump or of challenging any orders Trump may issue granting immunity to members of his staff before he leaves office. One adviser said Biden has made it clear that he “just wants to move on.”

Another Biden adviser said, “He’s going to be more oriented toward fixing the problems and moving forward than prosecuting them.”

Any decisions by Biden’s Justice Department regarding Trump, his staff, his associates, his business or his policies wouldn’t affect investigations by state officials, including Manhattan District Attorney Cyrus Vance Jr., who has fought to obtain Trump’s tax returns.
