CNN: McCain's campaign released a television ad Tuesday that builds on McCain's argument that Obama is not ready to lead.
"In crisis, experience matters. McCain and his Congressional allies led," an announcer says in the 30-second spot.
"Obama and his liberal allies? Mum on the market crisis," the announcer says.
Words beside a picture of Obama read "no leadership" as the announcer says, "A risk your family can't afford."
In response to the ad, the Obama campaign charged that McCain is the candidate who has not shown leadership.
"This ad is laughable. If you believe John McCain, George Bush and the Republicans in Washington have led on reforming Wall Street and restraining CEO pay, I've got a bridge in Alaska to sell you," said Obama-Biden spokesman Bill Burton.
