In a Thursday news conference, Ryan was asked if he would denounce Trump's candidacy given his previous criticism of the GOP front-runner's Muslim ban proposal and failure to quickly disavow the Ku Klux Klan.
"I do not believe that I'll have to do that," Ryan said.
"This is a democratic process. The Republican primary voter is going to make this decision on who our nominee is going to be. If the person doesn't get sufficient delegates, then it goes to the convention and the delegates make that decision," said the speaker of the House.
"I'm going to respect that process. So it isn't my place to say who our nominee is or what," he said.
