Update at bottom: The Secret Service is looking into Nugent's remarks.

The chairwoman of the Democratic National Committee (DNC) on Monday called on presumptive Republican presidential nominee Mitt Romney to disavow conservative rocker Ted Nugent after he encouraged members of the National Rifle Association (NRA) to defeat Democrats and “chop their heads off in November.”

"Mitt Romney surrogate Ted Nugent made offensive comments about President Obama and November’s elections this weekend that are despicable, deplorable and completely beyond the pale," DNC Chair Debbie Wasserman Schultz said in a press advisory. "He called the Administration 'vile,' 'evil' and 'America-hating,' and said much worse."

She continued: "Yet what have we heard from Mitt Romney and the Republican Party, who should be outraged that someone representing them is using language like this to make a political point? Absolutely nothing."

"Mitt Romney must condemn Nugent’s violent and hateful rhetoric immediately, as it has no place in our political discourse or this campaign."

Over the weekend, Nugent told the NRA crowd that they "should be to get a couple of thousand people per person who’s here to vote for Mitt Romney in November."

"If you don’t know that our government is wiping its ass with the Constitution, you’re living under a rock some place. And that there’s a dead soldier, an airman, a Marine, a seaman, a hero of the military that just got his legs blown off for the U.S. Constitution, and we got a president and an attorney general who doesn’t even like the Constitution," he said, adding that the four left-leaning Supreme Court justices were "like a stoned hippy" because they "don’t believe in the Constitution."

“And if you want more of those kinds of evil, anti-American people in the Supreme Court then don’t get involved and let Obama take office again. Because I’ll tell you this right now, if Barack Obama becomes the president in November again, I will either be dead or in jail by this time next year.”

Nugent continued by urging attendees to get everyone they knew to vote for Romney and against “this vile, evil, America-hating administration” or “we’ll be a suburb of Indonesia next year.”

“We need to ride into that battlefield and chop their heads off in November!” he exclaimed. “Any questions?”

In March, Nugent announced on Twitter that he had endorsed the former Massachusetts governor.

“[A]fter a long heart&soul conversation with MittRomney today I concluded this goodman will properly represent we the people & I endorsed him,” Nugent wrote.

Romney’s son, Tagg Romney, quickly praised the rocker.

“Ted Nugent endorsed my Dad today,” the younger Romney tweeted. “Ted Nugent? How cool is that?! He joins Kid Rock as great Detroit musicians on team Mitt!”

Update (1:20 p.m. ET): New York magazine reports that the Secret Service is looking into Nugent's comments as a possible threat on the president's life.

"We are aware of it, and we’ll conduct an appropriate follow up," a spokesperson for the agency said.

According to Right Wing Watch, Romney actively sought Nugent's endorsement.
