Ted Nugent recently said presumptive Republican presidential nominee Mitt Romney's campaign "expressed support" after the musician made comments that caused the U.S. Secret Service to wonder if he had threatened the life of President Barack Obama.

In a recent interview where the conservative rocker flew into a rage, Nugent revealed to CBS reporter Jeff Glor that he had spoken to Romney's campaign after he told a crowd at the National Rifle Association (NRA) convention that he would be “either be dead or in jail by this time next year” if Obama was re-elected.

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

Glor wondered if the Romney campaign was "unhappy" over those remarks.

"No," Nugent replied. "They expressed support. ... I got the sensation that it was -- not from Mitt himself or Ms. Romney -- 'Stay on course, Ted.' Freedom of speech is beautiful thing."

The Romney supporter recalled that he had an "adorable" meeting with the Secret Service for as long as 40 minutes after making the controversial comments.

"I feel sorry for liberals who can be that brain dead as to take a clear statement of fear on my part and turn it into a threat against somebody else," Nugent explained.

"If Mitt Romney wins, he needs at least some of the moderate vote," Glor noted. "You are many things, you are not moderate."

"Call me when you sit down across from someone who has more families with dying little boys and girls who get a call to take them on their last fishing trip in life!" an enraged Nugent screamed. "Call me when you meet someone who does that more than I do because that's really moderate! In fact, you know what that is? That's extreme! I'm an extremely loving, passionate man! And people who investigate me honestly -- without the baggage of political correctness -- ascertain the conclusion that I'm a damn nice guy! And if you can find a screening process more powerful than that, I'll suck your f*cking d*ck!"

"Or f*ck you!" he said, turning to Glor's female producer. "How's that sound?"

Glor told CBS hosts Charlie Rose and Erica Hill that Nugent later offered a "full apology" for his outburst.

"Yesterday, he called me on the phone after we got back from New York," Glor said. "And said after our interview, he was rushed to the emergency room and had a kidney stone removed. So, that's what he said may have contributed to his high level of energy."

The CBS reporter added that Nugent's musical career was not suffering because he is "more known now" after the controversial comments.

"His quote to us was that his 'guitar eats faces,' as only Ted Nugent can say it."
