Greg Sargent noted that he has heard rumors for days that Republicans would use "don't ask, don't tell" repeal as an excuse not to pass START.

"This isn't really a threat on Corker's part," Sargent wrote. "Rather, he's saying -- in a more-in-sorrow-than-in-anger way -- that his GOP colleagues will be less likely to support START unless Reid drops his plan for DADT and DREAM votes right away."
