At least five members of Congress are saying that Samantha Power, Sen. Barack Obama’s chief foreign policy adviser, should be fired. Power made remarks yesterday calling Sen. Hillary Clinton a “monster.” Power has since apologized, but Obama himself has said in the past that such “slime politics” should not be tolerated.

“Personal attacks are not the way to convince voters that you’re capable of being president of the United States,” New York Rep. Nita Lowey, said in a conference call on Monday morning. “We’re calling on Senator Obama to make it very clear that Samantha Power should not be part of this campaign.”

“It’s really a very important test for Obama,” Lowey added, saying that whether Obama fires Power is a real “test of character.”

Rep. Gregory Meeks and several other top politicos, some who support Clinton, have repeated the call for Power’s firing.
