Leading the chorus is Senator Roscoe Conkling of New York, bearing the Grant banner aloft. He is surrounded by (clockwise from the left): George Robeson, who, as secretary of the Navy under Grant, was investigated by Congress on charges of allowing waste and favoritism in the Navy Department; William Belknap, who, as secretary of war under Grant, was impeached by the House for taking bribes from Indian Post traders, but resigned before the Senate voted on his removal; Senator James Donald "Don" Cameron of Pennsylvania; Senator John Logan of Illinois; Alexander Shepherd, the corrupt former head of the Board of Public Works for the District of Columbia (he is often compared to "Boss" Tweed of Tammany Hall); and Thomas Murphy, former collector of the Port of New York (the country's most important patronage position). Press and popular criticism of Grant's candidacy as a bald grab for power is indicated by the designation "Empire" atop the banner's pole.
