On May 18, 2007, Cornyn was involved in an altercation with the late Senator John McCain. During a meeting on immigration, McCain and Cornyn had a shouting match when Cornyn started questioning the number of judicial appeals that illegal immigrants could receive. McCain yelled an insult at Cornyn and said "I know more about this than anyone else in the room." Previously, Cornyn told McCain, "Wait a second here. I've been sitting in here for all of these negotiations and you just parachute in here on the last day. You're out of line."
