IANAL but I could make a strong case for:
18 USC 599 Promise of political appointment by candidate
18 USC 600 Promise of employment or other benefit for political activity
18 USC 601 Deprivation of employment or other benefit for political contribution
18 USC 606 Intimidation to secure political contributions
18 USC 607 Place of Solicitation
18 USC 610 Coercion of Political Activity.
Just because he broke those laws openly and repeatedly and pretended those particular laws didn’t exist doesn’t mean that they don’t. And they should hit his corrupt cronies for violations of the Hatch Act.
That’s just for stuff he did while in office. I’m sure I could come up with more if I were a lawyer, or if I had more than 15 minutes this morning to research.
Then there’s the crimes he committed post-election.
18 USC 2383 - Rebellion or Insurrection
18 USC 2384 - Seditious Conspiracy
18 USC 2385 -Advocating for the Overthrow of the US Government
18 USC 2389 -Recruiting for Service against the United States
