Ed Schultz, a syndicated radio talk show host, called McCain, the Arizona senator who is the presumptive Republican nominee, a "warmonger" at a warm-up rally in North Dakota for Obama, the Illinois senator who is battling Sen. Hillary Clinton, D-N.Y., for the Democratic nomination.
Obama was not in the room at the time of the comments, though McCain called for Obama to distance himself from the categorization, The New York Times reported Sunday.
"I would hope … that Senator Obama would condemn such language, since it was part of his campaign," McCain told reporters in Arizona.
Jen Psaki, an Obama spokeswoman, said that while the candidates differ on their stance on the Iraq war, "John McCain is not a warmonger," a Psaki statement read.
"(McCain is) a supporter of a war that Senator Obama believes should have never been authorized and never been waged."
