McCain on rise of ISIS: 'We predicted this'

Sen. John McCain slammed President Barack Obama on Monday over his comments that U.S. intelligence underestimated ISIS.

McCain countered Obama's assertions made on CBS' "60 Minutes," saying that ISIS' expansion in Syria and Iraq was tied to the President's decision not to leave a residual U.S. military force in Iraq and his refusal to arm moderate Syrian rebels last year despite urgings from his national security advisers.

"We predicted this and watched it," McCain said on CNN's "New Day." "It was like watching a train wreck and warning every step of the way that this was happening."
