FactCheck.org:

"Cheney got our domain name wrong -- calling us "FactCheck.com" -- and wrongly implied that we had rebutted allegations Edwards was making about what Cheney had done as chief executive officer of Halliburton.

In fact, we did post an article pointing out that Cheney hasn't profited personally while in office from Halliburton's Iraq contracts, as falsely implied by a Kerry TV ad. But Edwards was talking about Cheney's responsibility for earlier Halliburton troubles. And in fact, Edwards was mostly right." [emphasis mine]

Funny. FactCheck.org also dug up a quote refuting Cheney's assertion that the Vice Presidential debate was the first time he had met Senator Edwards.

"Now, in my capacity as vice president, I am the president of Senate, the presiding officer. I'm up in the Senate most Tuesdays when they're in session. The first time I ever met you was when you walked on the stage tonight."

FactCheck.org turned up the following, attributed to Cheney in February of 2001:

"Thank you. Thank you very much. Congressman Watts,
Senator Edwards, friends from across America and distinguished visitors to
our country from all over the world, Lynne and I are honored to be with you
all this morning."

ABC News also turned up a few other instances when the two have met. It leaves me wondering why Cheney would make such an easy-to-refute lie.
