President Trump has been invited by Speaker of The US House of Representatives Nancy Pelosi and US Senate Minority Leader Chuck Schumer to testify during the impeachment inquiry to “speak all the truth he wants” and not attack witnesses, or call them #nevertrumpers.
The Never Trump movement also called #nevertrump, #anti-Trump, #StopTrump, or #DumpTrump, began as an effort on the part of a GOP group and prominent conservatives known as Never Trump Republicans to practice Donald Trump damage control.
A Never Trumper brings about change from within and perhaps they don’t see Trump as a member of their Republican party, an inappropriate spokesperson, etc., or worse- a danger to diplomatic relations.
A Never Trumper exposes corruption in The Whitehouse, may have tired of the growing ugliness in the face of such acts as caging immigrants. In this climate, who can speak well of Trump other than Trump?

Congressional leaders agree POTUS should give his side of the story rather than grumble about the proceedings on Twitter.
