Republican presidential candidate Jeb Bush said on Monday that he would "eliminate" the Supreme Court decision known as Citizens United that paved the way for the influence of super PACs in the electoral system.

"If I could do it all again I'd eliminate the Supreme Court ruling" Citizens United, Bush said in an interview on Monday, according to CNN. "This is a ridiculous system we have now where you have campaigns that struggle to raise money directly and they can't be held accountable for the spending of the super PAC that's their affiliate."

Bush reiterated his position during a campaign stop in New Hampshire, saying, "The ideal situation would be to overturn the Supreme Court ruling that allows for...unregulated money for the independent and regulated for the campaign," according to The Hill.

The irony was not lost on Donald Trump, who took to Twitter to highlight a degree of hypocrisy in Bush's newly-found position, given the support he receives from Right To Rise, a super PAC that raised $120 million to put Bush in the White House, Politico reported.

"Now that Bush has wasted $120 million of special interest money on his failed campaign, he says he would end super PACs. Sad!" Trump tweeted.

"I would turn that (Citizens United) on its head if I could," Bush said at a luncheon in Nashua, New Hampshire before the early voting state's primary on Tuesday, according to CBS News.

However, Bush seemed just as bothered by the personal nature of attack ads, as anything else.

"I mean, I just saw a mailing that attacked me through my mother with one of the super PACs," Bush told CNN. "C'mon man, that's a pretty low blow."
