The Missouri senator said there are a lot of reasons that ISIS rose up, citing a Status of Forces Agreement (SOFA) that President George W. Bush negotiated.
“We couldn’t leave our troops in Iraq, even if the president wanted to because the parliament in Iraq was refusing to give them immunity,” McCaskill said on “Fox News Sunday.”

“Now, Trump probably thinks the SOFA…is a gilded couch at Mar-a-Lago, he probably doesn’t even know what SOFA is, but that was a very relevant part of the this,” she continued.

“It was also important to realize that [Syrian President Bashar al] Assad, by what he did in his country, allowed ISIS to move into…Syria and get strongholds and recruit. That was the work and support of [Russian President Vladimir] Putin, who is Trump’s best buddy. So you can say Trump and his friend Putin are the founder of ISIS, which probably would be more accurate than calling out the commander in chief in that way.”
