In a "60 Minutes" profile that aired Sunday, Ryan told interviewer Scott Pelley he doesn't advocate the GOP presidential front-runner's plan to deport every illegal immigrant.
"I can't imagine how it could happen," Ryan said.
Ryan, who at 45 is the youngest House speaker since the 1860s, said he doesn't see the job as a long-term proposition.
"I was just planning on serving out my tenure as Ways and Means chair, and then going finding out something else to do with my life," he said. "I really don't know how long this is going to last. This wasn't something I was planning on doing in the first place." In fact, Ryan had to have his arm twisted to take the job. He has three children between the ages of 10 and 13 and said he didn't want to spend weekends away from them and attending fundraisers all over the country.
He believes he can find common ground with Democrats on highway infrastructure funding, tax policy and funding the government.
"Those are three things that will produce certainty in this economy in the next few months," he said. "Let's go do that."
