My reading of the Constitution makes it clear the only gov entity that can try a sitting president for anything (High crimes and misdemeanors) including actions of a President while in office is Congress. Courts are preempted
Congress has authorized lower federal courts to have “concurrent jurisdiction” with the SC over cases such as a state vs. the Feds. This jurisdiction needs to be removed by Congress. Simply changing SC justices won’t solve the root of the problem.
More specifically only the Senate has any trial power. The House is like a Grand Jury.
