Is the President's Ukraine diplomacy paying off or failing? At 6:30pm ET on Crossfire, Sen. Lindsey Graham (R-SC) and Sen. Ben Cardin (D-MD) go head-to-head in a debate joined by Newt Gingrich and guest host Sally Kohn.

Sen. Graham has been highly critical of the President’s foreign policy, calling him "weak and indecisive" and going as far as blaming Russia’s invasion of Ukraine on Benghazi.

In a CNN Opinion column, Kohn argues that the Republican attacks on Obama are hurting America’s global standing.
