Ultimately, Congress.

But the odds of getting the majority vote in the Republican-controlled House and 2/3 majority vote in the Republican-controlled Senate required to remove Trump from office are unlikely to be any better.

At least not until Republican primary voters start voting out pro-Trump Republicans in favor of candidates who don't pledge unwavering loyalty to a President who openly opposes institutions they (the voters) hold dear, like the free market, say, or the Pope.

Or just bite the bullet and vote for a Democrat they may agree with less, but trust more.
