In this exclusive to the Capitol Hill Broadcasting Network, presidential candidate Rep. Dennis Kucinich (D-Ohio) says oil explains why U.S. troops are still in Iraq and tensions between the United States and Iran are escalating.

"What's going on here? Think oil. Think Iraq, oil. Think Iran, oil. Because the reason why we're not leaving Iraq at this moment is because the United States wants to protect corporations access to the oil of the people of Iraq," he said.

"It's really time that we ended these corrupt politics that we have in this country where all these politicians are saying all options are on the table with respect to Iran, meaning even a nuclear attack," Kucinich added. "And yet, apparently, diplomacy's not one of those options."
