A U.S. congresswoman is warning that while the world's eyes are on Iran's growing threat against Israel, the Islamic nation's terrorist surrogates may have already formed sleeper cells here in the United States.

Rep. Sue Myrick, R-N.C., asserted in a radio interview today she believes it's possible that Hezbollah, the radical terrorist organization tied to Iran, may be working with Mexican cartels to funnel not only drugs, but also terrorist sleeper agents into the U.S.

"Former [Defense Intelligence Agency] people and others have told me what is going on, there have been a couple of arrests in this country relative to people who have had ties to Hezbollah or Iran, and my concern has been with the drug cartels and the gangs that are operating in Mexico," Myrick said. "There is, what I have been told, a very strong presence there of coordination between the two."

Myrick was speaking to Aaron Klein, host of "Aaron Klein Investigative Radio," which airs from 7-9 p.m. Eastern on New York's 77WABC Radio and is also streamed live on the Internet.

"I'm very concerned about the fact that they've been in Central America and South America for so long - we all know that, that's a recognized fact - and our border is not secure," Myrick continued. "We do not know who is in this country, and I really believe because of what is happening, because of the growing presence of Iran, their influence in those areas – and it is a growing presence – that there is just an opportunity for them, with our weak border that we have, to come into our country."

Myrick explained that she has been asking the Obama administration for years to expand its drug and border investigations to include activities of terrorists funneling through, "but there just hasn't been any movement whatsoever to get this done."

Klein asked Myrick why the Obama hasn't moved the Department of Homeland Security to action.

"I have no idea," she answered, "[but] one of these days we're going to wake up with a very big surprise."

Klein further pressed his guest about Iran's nuclear aspirations and the possibility that having surrogate Hezbollah agents crossing the U.S.-Mexican border could bring the worst of Islamic terror to the U.S.

"A lot of people think the Iranian threat is thousands of miles away – it's all about Israel, it's all about the Middle East, it doesn't affect the United States," Klein said. "Yes it does! They could give nuclear capability to Hezbollah, and then we're talking about suitcase nukes, EMP threat, who knows?"

Myrick confirmed both she and her contacts in the Drug Enforcement Administration are "very concerned" about "what have they already brought into the country and where is it and what can they do to cause harm to us, because that's their intention. It's no secret. They publicly say that."

Myrick has sounded the alarm before.

Earlier this year, after an alleged Iranian operative plotted to assassinate a Saudi diplomat in Washington using a hired gun on loan from a Mexican drug cartel, Myrick asserted the DHS was ignoring mounting evidence of a Hezbollah presence in Mexico.

"I don't have a lot of faith in the Department of Homeland Security," said Myrick. "They should be looking at these groups in Mexico much more closely."

DEA Administrator Michele M. Leonhart similarly told Fox News, "The dangerous connection between drug trafficking and terrorism cannot be overstated."

"Given the evidence available," Myrick also told Fox, "it only makes sense that DHS should, at the very least, investigate the presence of Hezbollah along our Southern border, regardless of who is in office."
