Why would Musk have to flee? Would the Dems charge him with a federal crime that trump already said he would pardon?

I hope the Dems have more teeth this time but what happens if Musk or whoever just doesn't show up to a subpoena, or just show but claim that every answer falls under executive privilege so they can't answer.

Whatever happens I hope the Dems are smart enough to pick different leaders in both chambers. We don't need any more of Jeffries or Schumer.
