(CNN) - An aide to Sen. Rand Paul who had taken heat recently for his past as a pro-Southern secessionist has resigned his position as the senator's new media director.
Moira Bagley, Paul's spokesperson, confirmed Monday that Jack Hunter had submitted his resignation and the senator has accepted it.
Hunter, who once used the persona "Southern Avenger" while hosting a radio show, will resume his career as a political pundit, according to the Daily Caller.
"I've long been a conservative, and years ago, a much more politically incorrect (and campy) one," Hunter said in an email to the conservative news outlet. "But there's a significant difference between being politically incorrect and racist. I've also become far more libertarian over the years, a philosophy that encourages a more tolerant worldview, through the lens of which I now look back on some of my older comments with embarrassment."
Hunter had made a number of provocative comments about race and was also a member of the pro-Southern independence group League of the South before he started working for Paul.
Hunter had previously written articles praising John Wilkes Booth, who assassinated Abraham Lincoln, and acknowledged that he toasts Booth's birthday annually.
The character "Southern Avenger," which Hunter described on his website as an "anonymous super hero/ pro-wrestler persona," wears a mask printed with the Confederate flag. The website is temporarily offline.
Paul, who is considering a bid for the 2016 GOP presidential nomination, has spent much of his trips to early voting states this year encouraging a more welcoming attitude among Republicans. The Kentucky Republican told a crowd of New Hampshire GOP activists the party needs to "grow bigger."
"If you want to be the party of white people, we're winning all the white votes. We're a diverse nation. We're going to win when we look like America," he said in May.
