US Speaker of the House, Paul Ryan, may be on friendlier terms with presumptive GOP nominee Donald Trump, but it does not mean he is completely sold on him. The Wisconsin Republican made peace with the billionaire real estate mogul earlier this month, but has yet to endorse his candidacy and has said he is not "betting" on a Trump win in November.

"I'm not going to—I'm not a betting man," Ryan said about the possibility of Trump winning in the general election during an interview with POLITICO's Glenn Thrush on Off Message. He added, "I think if we get our party unified, and if we do the work we need to do to get ourselves at full strength, and if we offer the country a clear and compelling agenda that is inspiring, that is inclusive, that fixes problems, that is solutions-based and based on good principles, then, yes, I think we can win."

When asked if he'll continue calling out Trump, Ryan did not hesitate to confirm that he will. "I've done that in the past, and I will do that in [the] future if need be, and I hope it's not necessary." Ryan said he believes Trump is a conservative "at his core" and said his party's likely candidate's chance in November. He also predicted the rise of "Trump Democrats".

Ryan did praise Trump for his ease and ability to speak frankly. "I think he's refreshing in that he takes on political correctness...the off-the-cuff, more natural, unscripted element is what is refreshing to people," he said, before adding, "within limits."

Earlier in May, Ryan said he was "not ready" to support Trump despite being the only remaining GOP candidate. The pair met a week later to discuss efforts to unite the party. According to CBS News, Ryan later told reporters he was "very encouraged" by Trump, who he referred to as a "warm and genuine" person. Trump is still 68 delegates short of officially clinching the party's nomination.

A recent CBS News/New York Times national poll revealed likely Democratic nominee Hillary Clinton's lead over Trump has narrowed. Clinton leads Trump 47% to 41% in a general election matchup, while her rival Bernie Sanders would defeat Trump by larger margins, 51% to 38%.
