Chris Matthews joked that Dick Cheney should waterboard Karl Rove on his Monday show.
Matthews, who said Cheney had a "good torture advocate name," played a clip of the former vice president saying that he regretted that torture methods like waterboarding had fallen out of favor after the Bush administration.
"I have got an interesting thought," Matthews said. "Why don’t have we have Cheney try that water-boarding thingamajig of his on Karl Rove and Scooter to really find out who said what in that CIA leak case? I think they are fair game, to use a phrase."WATCH:
