In August, the 1968 Democratic National Convention was held in Chicago. Intended to showcase Daley's achievements to national Democrats and the news media, the proceedings during the convention instead garnered notoriety for the mayor and city, descending into verbal outbursts on the part of politicians, and a circus for the media. With the nation divided by the Vietnam War and with the assassinations of King and Robert F. Kennedy earlier that year serving as backdrop, the city became a battleground for anti-Vietnam war protesters who vowed to shut down the convention. In some cases, confrontations between protesters and police turned violent, with images of this violence broadcast on national television. Later, anti-war activists Abbie Hoffman, Jerry Rubin, and three other members of the "Chicago Seven" were convicted of crossing state lines with the intent of inciting a riot as a result of these confrontations, though the convictions were overturned on appeal. At the convention itself, Sen. Abraham A. Ribicoff (D-Conn.), went off-script during his speech nominating George McGovern, saying, "And with George McGovern as President of the United States, we wouldn't have to have Gestapo tactics in the streets of Chicago. And with George McGovern as president, we wouldn't have to have a National guard." Ribicoff, with his voice shaking, then said: "How hard it is to speak the truth, when we know the problems that are facing this nation", for which some in the crowd booed Ribicoff. Ribicoff also tried to introduce a motion to shut down the convention and move it to another city. Many conventioneers applauded Ribicoff's remarks but an indignant Mayor Daley tried to shout down the speaker. As television cameras focused on Daley, lip-readers later said they observed him shouting, "Fuck you, you Jew son of a bitch, you lousy motherfucker go home." Defenders of the mayor later stated that he was calling Ribicoff a faker, a charge denied by Daley and refuted by Mike Royko's reporting. A federal commission, led by local attorney, party activist Dan Walker, investigated the events surrounding the convention and described them as a "police riot". Daley defended his police force with the following statement, which was also a slip of the tongue: "The confrontation was not caused by the police. The confrontation was caused by those who charged the police. Gentlemen, let's get this thing straight, once and for all. The policeman is not here to create disorder.
