A Kerry ad implies Cheney has a financial interest in Halliburton and is profiting from the company's contracts in Iraq. The fact is, Cheney doesn't gain a penny from Halliburton's contracts, and almost certainly won't lose even if Halliburton goes bankrupt.
The ad claims Cheney got $2 million from Halliburton "as vice president," which is false. Actually, nearly $1.6 million of that was paid before Cheney took office. More importantly, all of it was earned before he was a candidate, when he was the company's chief executive.
