If there was a functioning DOJ, they could bring RICO charges against the whole administration, their business associates and involved family members, all of whom are co-conspirators to corruption of government and bribery. But that would never happen, of course, because Americans don't riot en masse and demand accountability for corrupt government officials.

It's the job of the Congress to hold the executive branch accountable, with the ultimate endpoint being impeachment and removal if necessary. Unfortunately, the Senate republicans are completely sold out to the cult of Trump so there will be no relief from that quarter.
