Lawrence O'Donnell tears into Liz Cheney for her remarks criticizing President Obama for his visit to Dover AFB. Liz Cheney lies again. Chip off the old block.

O'DONNELL: When President Obama honored our Afghanistan war dead by taking part in a military ritual at Dover Air Force Base yesterday, it was easily predictable that a Republican would criticize him for it. And in our fourth story on the Countdown, the former Vice President's pet attack dog, his daughter Liz Cheney, has now done just that. And once again, she wasn't going to let the facts get in the way.

On the John Gibson radio show yesterday, Ms. Cheney was rehashing her father's fact-free critique of President Obama's war in Afghanistan, and then Mr. Gibson asked her about the President's appearance at Dover Air Force Base.

LIZ CHENEY (RADIO AUDIO): I don't know why he went to Dover. I mean, I think that clearly it is very important for a commander-in-chief, whenever he can in whatever way it possible, to pay tribute to our fallen soldiers, our fallen military folks. But, I think, you know, what President Bush used to do was do it without the cameras, and I don't understand sort of showing up with the White House Press Pool with photographers and asking the family if you can take pictures. I just... that's really hard for me to get my head around—I think it's an honorable and important thing for us to pay tribute. There's no greater sacrifice people make to the nation. But, it was a surprising way for the President to choose to do it.

O'DONNELL: As we mentioned yesterday, President Bush never went to Dover Air Force Base to honor dead American soldiers on their final journey. And Vice President Cheney... never did either.

Hey Liz, have you ever lost a relative in battle? I have. My cousin Johnny, West Point graduate like his father before him. I wish the President or the Vice President had met his casket on the way home.

You know what 'never' means, Liz? It means zero. It means that in over seven years of two wars, your dad never left the comfort of his White House office or the Vice President's mansion and got himself up to Dover to bear witness to how his warmongering fell on families of dead American soldiers. Never, not once.
