Trump spoke of this at one of his rallies before Ryan’s primary - said Pence called him. Trump said ‘He told me he didn’t want to be contrary to Trump’s wishes. Trump said ‘Mike, do you like the guy?’ “Yes”. ‘Fine. Then endorse him.’
I thought it was classy and mature of Trump - didn’t sweat it and let Mike do what he felt he had to do.
I don’t think any of us that are NOT GOP-e like him, so why would Pence? He may not be on the same page as us.
