Do you know how to tell when Democrats are lying? Their lips move.

Biden said Monday that it is “unfortunate” the White House continues to blame Democrats for Bolton’s inability to win confirmation.

Now let’s go back to June, 2005 and see why Bolton wasn’t able win confirmation… or even get an up or down vote at all:

Republicans failed for the second time Monday to move the Senate toward a vote on President Bush’s nomination of John R. Bolton to be ambassador to the United Nations.

The motion to close off debate on the controversial nomination fell six votes short of the three-fifths majority of 60 required for cloture. The vote was 54-38 — largely along party lines.

An attempt by the Senate’s Republican majority to cut off debate failed in May when most of the 44 Democrats refused to join the 55 Republicans and move toward a final vote.
…
Democrats said they would continue to block Bolton’s nomination until the White House produces records of communications intercepts he sought from the National Security Agency.

Yep, the Democrats were filibustering the nomination. And just who was the ranking Democrat on the Foreign Relations Committee, the committee in charge of recommending Bolton’s nomination to the full Senate, for an up or down vote on confirmation?

Why, Joe Biden, of course.
