Lieberman remains a filibuster threat

From NBC's Chuck Todd and Mark Murray
Earlier this morning, we clipped an article from The Hill, which reported that Sen. Joe Lieberman (I-D) "has reached a private understanding with Majority Leader Harry Reid that he will not block a final vote on healthcare reform."

But not so fast...

Lieberman communications director Marshall Wittmann emails First Read, "If you believe this story is true, you will also believe that I am replacing A-Rod in game six of the series."

Translation: Lieberman remains a threat to filibuster the Senate health-care bill, if it contains a public option.
