On "Hannity" tonight, Sen. Ted Cruz (R-TX) said that if President Obama's nuclear agreement with Iran goes through, the Obama administration will become the world's leading financier of radical Islamic terrorism.

Cruz pointed out that Obama attacked the GOP today, as opposed to disputing the fact that the nuclear deal empowers jihadists.

Cruz extended an invitation to Obama to debate the substance of the nuke deal at any time and place of the president's choosing.

"If he's so convinced he's right on the substance, I will welcome him anytime. And if he's unwilling to show up, he can send as a proxy John Kerry," Cruz said. "Let's debate the substance of how much this endangers the United States of America, Israel and the world."

"It's the single greatest national security threat facing America."
