Donald Trump on Friday dismissed comments from House Speaker Paul Ryan in which the Wisconsin Republican said voters should follow their conscience on the presumptive GOP nominee.
"He's got to do what he's got to do," Trump told NBC News when asked to react to Ryan's latest remarks.
"If they can't stay positive, they should probably not say anything at all because I'm going to win the race," Trump added.
Earlier in the day, Ryan told "Meet the Press" host Chuck Todd that he won't push members of his GOP conference to back the billionaire businessman in the general election.
"The last thing I would do is tell anybody to do something that's contrary to their conscience," Ryan said.
On Thursday, Ryan said he had no plans to rescind his endorsement of Trump, which he made earlier this month, even though they disagree on a number of key issues including Trump's proposed Muslim ban.
"That's not my plan. I don't have a plan to do that," Ryan told reporters when asked if there's a chance he could withdraw the endorsement.
Ryan will serve as chairman of the Republican National Convention in Cleveland next month.
