On Rep. Paul Ryan, his former running mate and House Budget Committee chair: Oh, I love Paul. I mean I will always have a very special feeling for Paul, because I think he was one of the great vice presidential nominees in history. I think he would have been a terrific vice president. I don't have any idea whether he has presidential aspirations."
On Sen. Rand Paul, R-Kentucky: "Rand is also a very strong emerging voice in the Republican Party. Represents a different, if you will, vocal group within the party that's having a real impact.
"And with those three that happen to all be coming (Christie, Ryan and Paul), you're going to see three very different Republicans - one a governor, one a member of Congress who's a conservative, a long-term conservative; another who represents a more libertarian wing of our party. And each presenting their views about priorities. It's going to give us a chance to hear from all three and decide from - for ourselves what we think the right path will be."
On former Secretary of State Hillary Clinton: "Secretary Clinton's challenge will not just be Benghazi, but more the record of American foreign policy over the last four years, while she was secretary of state.
"We'll look at everything from North Korea to Iran to Pakistan, to Afghanistan, to Syria, to Egypt and you look across the world, and our prospects - the prospects for stability, for liberal democracy, for freedom, have retreated over the period of her administration in the Department of State. And I think that's something that - that it will be a challenge for her."
Asked about one of the biggest stories of the day-the IRS' admitted targeting of tea party and conservative groups that sought tax-exempt status-Romney said the incident was a "breach of trust" and argued the administration was purposely keeping the controversy under wraps during the campaign.
"I think they certainly hid the activities of targeting conservative groups. Otherwise, there would have been a hue and outcry about it," he said.
Romney did not go as far as saying the line of fault runs all the way up to the president's desk-as some other Republicans are attempting to prove-but said "time will tell" on who was involved.
Asked if he thinks it would have changed the outcome of the election had the public known about it, Romney said the results were so close--51% to 47%--that "a number of things could have changed the outcome."
"Again, you don't look back and say, oh, couldn't we have just changed this?" he said "The president won. I congratulate his campaign team on having won. That's the nature of politics is winning. They won. Nice work. And let's get on with it."
Another issue in the Washington spotlight is immigration. Romney was famously known for saying in the GOP primary that he supported a policy of self-deportation, in which undocumented immigrants would voluntarily return to their countries and apply for legal re-entry.
Since the election loss, many Republicans have noted his comments as having a damaging effect on the party's image and some in the party have taken an aggressive approach to tackle immigration reform.
In the interview, Romney attempted to clarify what he meant by the term.
"It's interesting how the opposition campaign made a big deal of that. Self-deportation is as opposed to government deportation. The government deports people. Now, my view was that people should make their own choice. And so, people say, oh, he's for self-deportation, it sounds very, very, unkind."
Romney said his plan was "overtaken by events." While he favors some of the current proposals and disagrees with others, the Republican acknowledged "it's not my choice at this stage."
"But let's deal with the 11 million, and let's reform the legal system so the millions who are in line can understand how to get here legally and we can bring in those people that our economy needs and, frankly, that families we'd like to have reunited to come in legally," he said.
