When Sen. Joe Lieberman (I-Conn.) retires from the upper chamber he will leave behind a gap in the “three amigos” on foreign policy, as he and Sens. John McCain (R-Ariz.) and Lindsey Graham (R-S.C.) have been dubbed. The three senators traveled the world together for over a decade and were always at the table for foreign policy debates. Through bipartisan measures, these three senators have championed wars and solutions for global humanitarian crises.

It seems that a trio will remain intact even as one member bows out. Lieberman has found a successor in Sen. Kelly Ayotte (R).
