 -- A day after announcing his support for Donald Trump's presidential campaign, House Speaker Paul Ryan condemned his party's presumptive presidential nominee for his comments about a federal judge's ability to be objective in a case involving the now-defunct Trump University.

"The comment about the judge the other day was out of left field, for my mind," the Wisconsin congressman said in an interview with Vicki McKenna, a conservative radio host there. "I completely disagree with the thinking behind that."

On Thursday, just hours after Ryan said he would vote for Trump in November, the New York businessman told The Wall Street Journal that U.S. District Court Judge Gonzalo Curiel, who is presiding over a lawsuit by former Trump University students, has an "absolute conflict" of interest in the case because of his Mexican heritage. Trump has strongly opposed illegal immigration, claimed Mexico sends criminals to the U.S. and promised to build a wall along the length of the U.S.-Mexico border.

Curiel, who was born in Indiana, is of Mexican descent.

"He clearly says and does things I don't agree with," Ryan said of Trump. "I've had to speak up from time to time when that has occurred, and I'll continue to do that when it's necessary. I hope it's not."

While he has clashed with Trump over the businessman's rhetoric and more controversial proposals, Ryan believes that as president, Trump would be more likely to support House Republicans goals than Hillary Clinton would.

"Donald Trump can help us make it a reality," Ryan wrote in the Thursday op-ed in The Janesville (Wisconsin) Gazette announcing his support for Trump.

In a video released by his office today, Ryan previewed the GOP election-year agenda, titled "A Better Way." He and House Republican leaders will unveil its poverty and national security policies next week.
