On December 28, 2009, Stein appeared on CNN's Larry King Live with Ron Paul to discuss the attempted bombing of an American plane on Christmas Day 2009. Stein said that Paul's stance that the United States were "occupiers" in Iraq and Afghanistan "is the same anti-Semitic argument we've heard over and over again." The comment started a shouting match between the two men and prompted anger from Paul supporters and those who believe Stein went too far in calling Paul's argument anti-Semitic. Stein issued an apology on December 30, 2009.
