Not really, I’m on the phone now but Walker met up with Pres in the Oval office, they made up. He was no big Never Trumper.
Yes, they had some differences at one time.
Maybe they made up, but Walker was virulently NeverTrump at the end of his 2016 presidential bid.
On his way out of the race, he exhorted the remaining candidates to destroy Trump. It was an unbelievably nasty statement.
