President Trump called for Mitt Romney's impeachment because Romney criticized his attempt to extort the president of the Ukraine for personal political gain. Of course, US senators can't be impeached. They can be expelled from the Senate but certainly not for criticizing a president.
I’m hearing that the Great People of Utah are considering their vote for their Pompous Senator, Mitt Romney, to be a big mistake. I agree! He is a fool who is playing right into the hands of the Do Nothing Democrats! #IMPEACHMITTROMNEY— Donald J. Trump (@realDonaldTrump) October 5, 2019
