Dem: Some Tea Partiers 'domestic enemies'

"A lot of those members are rabid," Cohen told MSNBC. "They're sophomoric — literally their second term of Congress — they've never worked in politics before and they think they are somehow … it was all talked in military terms. They think they are some kind of guerrillas there to strike a blow for freedom. I think they may try to pull this off again."

Cohen said that to avoid another showdown over government funding or the debt ceiling, Speaker John Boehner (R-Ohio) would need to decide he did not want to retain his gavel, and instead work to strike bipartisan agreements that ignored the wishes of the Tea Party.

"Work with the same crew that gave us the opening-up of government: Nancy Pelosi's Democratic caucus and give or take 80 reasonable Republicans and pass some bills to avoid another [continuing resolution] problem and shutdown and avoid the debt crisis," Cohen said.

Cohen said that would be the only way to "protect the country from these people."

Really, you got to think — we take an oath to support the country against all enemies, foreign and domestic,” Cohen said. “These are the domestic enemies."

Federal officials, including members of Congress, swear an oath to "support and defend the Constitution of the United States against all enemies, foreign and domestic."
