Chris Matthews called Rush Limbaugh, Glenn Beck and other conservatives who are skeptical of climate change "evil" on his Wednesday show.
Matthews was discussing Al Gore's recent article in Rolling Stone, in which Gore criticized President Obama for not doing enough to combat climate change.
Matthews said he was astonished that people like Limbaugh and Beck flatly deny that climate change is happening.
"Rush Limbaugh says stuff that is just non- well, is just not true," he said. "I never use the word lie, but it's appropriate here."
He then turned to Beck.
"People like, you know, Glenn Beck, I heard him months or years ago on the radio before he was on TV saying there's no climate change, playing, pandering to these business types, pandering to people who don't want to deal with reality," he said, his voice rising. "These people are evil in what they're doing! I'm not saying their souls are evil, but what they're doing is really, really wrong and it's not the President. It's this corrupt media on the right. You know, it's corrupt media on the right."
Beck and Matthews have feuded before; most notably, Beck exploded at Matthews over his criticism of Michele Bachmann.Watch (comments begin at 5:26):
