Via Politico:

As Joe Lieberman winds down his two-decade career in the Senate, the onetime Democratic vice presidential nominee is reaching out to an unlikely group to help seal his political legacy: freshman Republicans.
Behind the scenes and in front of the cameras, the retiring foreign policy hawk is grooming, mentoring and partnering with a handful of GOP freshmen to ensure that, long after he’s left the Senate, his vision for America’s role abroad survives.
Reaching across the aisle is nothing new for Lieberman, who stood on the stage at the 2008 Republican National Convention and endorsed John McCain, making his choice of mentees — including Sens. Kelly Ayotte, Mark Kirk and Marco Rubio — a fresh reminder of how the former Democratic stalwart managed to find himself a near pariah among liberals.
At a recent news conference, Lieberman stood shoulder to shoulder with Ayotte (R-N.H.), promoting legislation that would block the Obama administration’s efforts to shutter the Guantanamo Bay, Cuba, terrorist detention center.
He and Kirk (R-Ill.) this month launched their U.S.-China Working Group, a forum for senators and Chinese officials to discuss such prickly matters as North Korea’s nuclear program.
When Natan Sharansky, the Russian-Jewish political prisoner and human rights activist, paid a visit to Lieberman’s office in March, the devout Jewish senator asked longtime Israel defenders, including McCain (R-Ariz.) and Sen. Frank Lautenberg (D-N.J.), to drop by. But he also invited Rubio, another staunch Israel backer, to the intimate meeting.
