This is just like Jerry Falwell Jr earlier today on CNN saying even if Trump was proven to have committed sexual assault it didn't matter, as long as he was there to appoint Supreme Court Justices to overturn Roe v Wade. Basically a lot of people just see Trump as a vehicle to fulfill their agenda, be it huge tax cuts or ending Abortion or whatever, and they essentially don't care about anything he does. He literally could kill that guy on Fifth Ave. But at least they are admitting it. Paul Ryan is really no different. He wants Trump to sign all those bills sitting in his desk and therefore he too will support him officially no matter what, but just doesn't want to be seen with him or speak up to defend him.
