'Washington's horribly broken,' Kentucky Republican Sen. Rand Paul said Tuesday, but it came in the midst of a TV interview broken up by prickly moments and interruptions. Paul, who launched his presidential campaign Tuesday in Louisville, Kentucky, sparred with TODAY host Savannah Guthrie about his past foreign policy positions. As Guthrie rattled off a list of issues where she said the senator had flipped and flopped – Iran, aid to Israel and defense spending – a testy and impatient Paul cut her off. 'Why don't we let me explain instead of talking over me, OK?' he griped. PRICKLY: Newly minted White House hopeful Rand Paul and NBC host Savannah Guthrie talked over each other on Wednesday . Paul, a libertarian-leaning Kentucky senator, launched his presidential bid on Tuesday in Louisville . 'No, no, no, no, no, no, no, no!' Listen, you've editorialized,' Paul blasted at Guthrie . 'Before we go through a litany of things you say I've changed on, why don't you ask me a question: "Have I changed my opinion?" That would be sort of a better way to approach an interview.' Guthrie obliged, asking him if he had changed his views, but he charged ahead. 'No, no, you've editorialized,' Paul said. 'No, no, no, no, no, no, no, no!' Listen, you've editorialized. Let me answer a question! You ask a question, and you say, "Have your views changed?" instead of editorializing and saying my views have changed.' A spokesman for American Bridge 21st Century, a liberal opposition-research group, leaped on Paul after the broadcast. 'Rand Paul can't seem to step in front of a camera without proving that shooting from the hip is a good way to shoot yourself in the foot,' Ben Ray told Daily Mail Online. 'He's got miles to go before his ability catches up to his ambition,' Ray added. 'And judging by his temper, he knows it, too.' When style gave way to substance on TODAY, Paul clarified that when he said in 2007 that Iran wasn't a threat to the United States, the world was different and he wasn't yet a candidate for the Senate. '2007 was a long time ago and events do change over long periods of time,' he said. 'So we're talking about 8 years ago. We're talking about a time when I wasn't running for office and I was helping someone else run for office.' That 'someone else' was his father, Ron Paul, a former congressman who ran for president three times but never grabed the brass ring. The elder Paul was known for strictly non-interventionist views overseas in the face of growing threats abroad, a trap that his son has taken great pains to avoid. 'There has always been a threat around gaining nuclear weapons and that's greater now than it was many years ago,' he said Wednesday. His troublesome 2007 moment came during an interview with conspiracy-theorist radio host Alex Jones. 'You know, it’s ridiculous to think they’re a threat to our national security,' Paul said then of Iran. 'It’s not even that viable to say they’re a national threat to Israel,' he added later. 'Most people say Israel has 100 nuclear weapons, you know.' On the TODAY show, Paul the younger avoided taking a stand on the nuclear agreement the White House says it has carved out with Tehran's mullahs. Paul was joined by his wife Kelley Ashby on stage Tuesday as he declared that he would campaign to 'take our country back' 'I'm going to keep an open mind and look at the agreement,' Paul said, while allowing that 'I do believe that negotiation is better than war.' He mirrored other Republicans in questioning the 'sincerity of the Iranians' in reaching an agreement with the U.S. and five European nations. 'If they're immediately saying that the agreement doesn't mean what President Obama says, that is a big problem,' Paul said. 'The Iranians put out 500 words, the Americans put out 1,300 words, the Europeans put out 200 words. And they don't all seem to agree, but it's very, very little information so far.' He defended his position on foreign aid, saying that even Israeli Prime Minister Benjamin Netanyahu has agreed that his country should one day shake off its dependence on America to fund its defense program. 'I still agree with my original precept, which is – lemme answer the question! – I still agree with my original statement from years ago that ultimately all nations should be free of foreign aid,' he said, 'because we shouldn't borrow money to do it.' 'But my opinion's not any different than Netanyahu's opinion.' The Paul campaign did not respond to a request for comment no whether or not Guthrie gave him a fair interview.
