Meghan McCain blasted Joe Biden for his controversial "chains" remarks on Tuesday, calling the vice president an "idiot" over his "race-baiting" comments.

During an interview on KTAR's "Mac and Gaydos" radio show, McCain spoke candidly about her distaste for Biden, who stirred controversy when he told a crowd of supporters in Virginia that Mitt Romney and other Republican candidates would "put y'all back in chains."

"I'm just so sick of this BS from [Biden]." McCain said. "I can't stand Joe Biden because I think stupid is worse than being mean."

"I just think any insinuation that in America we're going to go back to slavery times is delusional," McCain continued. "It's ridiculous and it is ignorant... If I were Obama, I would've never picked Joe Biden in the first place. I think he's an idiot. And I know people think it's cute because he's like crazy grandpa and they like his gaffes but I think it's offensive."

McCain wasn't the only one to lash out at Biden. Romney's campaign also criticized the vice president, accusing President Obama's reelection campaign of reaching a "new low."

Biden later clarified his remarks, noting that Romney's running mate Rep. Paul Ryan (R-Wis.) has also used the "unshackle" metaphor

"I'm told that when I made that comment earlier today in Danville, the Romney campaign put out a tweet … [and] went on the airwaves saying, 'Biden, he’s outrageous in saying that,'" Biden said. "I got a message for them. If you want to know what's outrageous, it’s their policies and the effects of their policies on middle-class America. That’s what’s outrageous."

The vice president also said that he meant to say "unshackled" rather than "unchained."

CORRECTION: In an earlier version of this article, the name of the radio show was misspelled. It's called "Mac and Gaydos."
