Sen. Joe Lieberman said Sunday that he believes that when Congress comes back into session this fall that Democrats will vote to extend tax cuts for the wealthiest Americans.

"We've got to extend these tax cuts," Lieberman told CNN's Candy Crowley.

Failing to extend the tax cuts is "the surest way to send America back into a second dip of a recession," he said.

"My guess is that the probability is that we will extend the so-called middle-class tax cuts permanently so to speak. And we will agree to extend the tax cuts on high income earners for at least a year or two," said Lieberman.
