House Speaker Paul Ryan supposedly has some imaginary line that Donald Trump can't cross without losing his endorsement. Ryan told radio host Charlie Sykes last Friday that Trump doesn't get a "blank check" endorsement from him. When pressed on where that line was, Ryan responded:

“Where that line gets crossed, I don’t know where that is,” he told Sykes.

How about suggesting a "Second Amendment" remedy to stop Hillary Clinton from appointing Supreme Court judges? Do assassination threats cross your line, Mr. Speaker?
