Sen. Lindsey Graham told Sean Hannity Tuesday night that the decision by Democrats to have former special counsel Robert Mueller testify will "blow up in their faces."
SEN. LINDSEY GRAHAM (R-SC): Bottom line is, after all of your looking and all the time you had and all the money you spent, did Trump collude with the Russians? No. Do you stand by your report? Yes.
It is case closed for me. They can do anything they want to in the House, and I think it will blow up in their face. It will blow up in their face. This will blow up in their face. The conclusions can't change, there is no collusion, that's what the whole thing was about to begin with.
