Former Secretary of Defense Donald Rumsfeld slammed President Barack Obama on Monday, saying "a trained ape" would have better foreign policy skills.

During an appearance on Fox News' "On the Record with Greta van Susteren," Rumsfeld criticized the White House for not securing a status of forces agreement with Afghanistan.

"We have status of forces agreements probably with 100, 125 countries in the world," Rumsfeld said. "This administration, the White House, and the State Department, have failed to get a status of forces agreement. A trained ape could get a status of forces agreement. It doesn't take a genius."
