Appearing on Wednesday’s “Hannity,” Wisconsin Gov. Scott Walker pushed back against President Barack Obama’s claim that he needs to “bone up” on foreign policy. Walker, who is an early frontrunner for the 2016 GOP nomination, blasted Obama for having “the audacity” to question anyone on foreign policy. He also hit Obama for being the one who “called ISIS the JV squad.” Obama made the comment to NPR in an interview Monday. “Think about that statement,” Walker began, “this is a guy who in the last year called ISIS the JV squad, who called Yemen, just last fall, and his administration continues to call them a success story, who had his secretary of state, under Hillary Clinton — that gave Russia a reset button, and then they ultimately went into the Ukraine. “This is a guy who I think — the audacity to be talking about schooling anyone when it comes to foreign policy,” Walker said.
