Sen. Rand Paul, R-Ky., has in recent months developed a love for taking potshots at former Secretary of State Hillary Clinton, which may have something to do with the fact that the two are likely considering running for president in 2016.

Paul’s latest criticism of Clinton calls into question her saying recently that climate change is one of the greatest threats currently facing the U.S.

Paul said Friday during an interview on Fox News: “For her to be out there saying that the biggest threat to our safety and to our well-being is climate change, I think, goes to the heart of the matter or whether or not she has the wisdom to lead the country, which I think it’s obvious that she doesn’t."

Clinton said earlier Thursday at the National Clean Energy Summit in Las Vegas that climate change has created for the U.S. “the most consequential, urgent, sweeping collection of challenges we face.”

But Paul doesn’t see it this way. In fact, according to the Kentucky senator and possible presidential hopeful, Clinton referring to climate change as one of America’s biggest threats shows she lacks the “wisdom” necessary to lead the nation.

“I don’t think we really want a commander-in-chief who’s battling climate change instead of terrorism,” Paul said.

The Republican senator’s remarks come on the heels of his recent criticism of Clinton’s handling of the State Department during the deadly Sept. 11, 2012, terrorist attack on U.S. facilities in Benghazi, Libya.

The Kentucky senator maintains that criticism of Clinton’s actions at the State Department in the days leading up to and preceding the attacks is not “politically motivated,” but that it is legitimate considering she may have her eye on the Oval Office.

"There will be discussion over the next four years whether or not Hillary Clinton is fit to lead this country," he said last week at an event in Dallas. "Is Hillary Clinton fit to be commander-in-chief?"

He continued, likening the events in Benghazi to the 1993 U.S. raid in Mogadishu, Somalia, that saw the death of 18 members of the U.S. armed forces. Not long after the disastrous events in Somalia, former President Bill Clinton announced the resignation of then-Secretary of the Defense Les Aspin, the man who denied repeated requests for increased security in that area prior to the deadly raid.

"He ignored the request and he resigned ultimately in disgrace," Paul said. "I think had Hillary Clinton worked for Bill Clinton, she'd probably have been fired."

Clinton has not yet responded in kind to Paul’s many criticisms.

But here's something worth considering: After Paul said earlier this year that the sordid scandal between Bill Clinton and Monica Lewinsky would be fair game if the former secretary of state makes a run for the White House in 2016, Clinton responded with a none-too-subtle warning: "He can talk about whatever he wants to talk about. And if he decides to run, he'll be fair game too."

A face-off between Paul and Clinton would most definitely be a terribly messy and bitter affair. But it would also probably be wildly entertaining. So at least we have that possibility to look forward to.
