“It was the first time I have had a candid conversation or a substantial conversation with a member of the Obama administration since they came into power,” the former GOP vice presidential candidate added.

The high-powered beer summit is the latest effort in a sustained second-term charm offensive undertaken by the White House to woo lawmakers on Capitol Hill. On Wednesday night, Obama met with House Democrats for dinner at the Jefferson Hotel, and earlier in the week he played golf with a trio of Republican senators. He's also met groups of Republican and Democratic senators for dinner either at the White House or a Washington-area hotel, and earlier in the year hosted Ryan for a working lunch.

"He's looking to get things done," White House press secretary Jay Carney said Monday of the president's outreach efforts. "And he wants to talk to anyone who has that as his or her objective too, and is willing to accept that they may not get everything they want out of a compromise — in fact, by definition, they will not — and they can live with that. Partisan purists are not what he's looking for. He's looking for people who want to go about the business of building the economy, helping the middle class, responsibly reducing our deficit, reforming our immigration system in a way that will help our economy and the middle class, and taking action to reduce gun violence.

"So if there is anybody who meets that standard, anybody who is willing to say, you know what, I accept that I'm not going to get my dream partisan agenda, I accept that I'm going to have to give a little bit, that I may have to compromise in order to achieve these objectives, then he wants to have that conversation."
