In a radio interview Tuesday, Sen. Rand Paul (R-Ky.) bristled at questions about Jack Hunter, his aide who recently resigned after his past comments in favor of secession and the Confederacy were revealed.

In response to John Harwood on NPR's "On Point," Paul answered sharply when Harwood raised the issue.

"Don't you have anything better — don't you have something better to read than a bunch of crap from people who don't like me?" he inquired pointedly.

“I don't accept all of that and I don't really need to or spend the time talking about all of that," Paul said of allegations of racism. "If you want to talk about issues and what I stand for, I'm happy to, but I'm not going to go through an interview reciting or respond to every yahoo in the world who wants to throw up a canard."

When Harwood mentioned Hunter's contribution to Paul's 2010 book, "The Tea Party Goes To Washington" to qualify his questioning, Paul countered, "You think you want to dwell on something and you want to dwell on critical articles of people who don't like me and don't support any libertarian ideals."

Paul, who is considered a potential presidential candidate in 2016, was featured on the show "On Point" to discuss the future of the GOP, particularly his brand of libertarianism.
