Senate Democratic Leader Harry Reid urged his deputies to "just relax" in their dispute over leadership posts after his retirement.

The dispute involves Sen. Charles Schumer of New York, who hopes to succeed Reid, and Sen. Richard Durbin of Illinois. Durbin pledged to support Schumer for the top job, his aides say, in the belief that Schumer would back Durbin for Democratic whip—the same post Durbin now holds.
