Senior aides to President Joe Biden have reportedly been considering the prospect of issuing preemptive pardons to certain officials in the wake of the president’s controversial pardon of his son, Hunter Biden.

The aides are alarmed by President-elect Donald Trump’s choice of Kash Patel for FBI director given his past statements that he would seek out Trump’s detractors, Politico reported, citing senior Democrats. They worry officials could be subject to inquiries or indictments for their past statements or actions.
