I’ve heard Trump say Boehner had to go and Boehner has attacked Trump.

Okay, I did find one example from Sep. 9th.

With Cruz speaking to the assembled crowd in the background, Trump didn’t quite come out in support of Boehner’s removal as speaker to a group of reporters, but he did say he was disappointed in him and his “vigor.”

“Well, it’s very disappointing,” Trump said of Boehner’s leadership in the House. “You know, I know him on a personable basis, I really like him a lot. But he’s been very disappointing in terms of his vigor and in terms of stopping Obamacare and many other things and certainly in terms of even this [stopping the Iran deal].”

But I would prefer more "vigorous" criticism.
