Washington, D.C. ? A political group supporting President Bush’s Iraq war strategy with a multimillion-dollar ad campaign is airing a new TV ad denouncing a liberal group’s sharp criticism of Gen. David Petraeus.

The campaign is the second rollout of ads by the group, Freedom’s Watch, and capitalizes on Democratic Party unease over a newspaper ad run this week by MoveOn.org, one of the leading anti-war voices among liberal activists.

The MoveOn ad appeared Monday in The New York Times on the morning of Petraeus’ first appearance before Congress to testify about conditions in Iraq. The ad accused Petraeus of “cooking the books” for the White House. “General Petraeus or General Betray Us?” it asked, playing off his name.
