WASHINGTON - APRIL 1: (L-R) U.S. Rep. Peter King (R-NY), Sen. John McCain (R-AZ), documentary filmmaker Ken Burns, Dorothy Cross, great niece of the first African American heavyweight boxing champion John Arthur 'Jack' Johnson, Cross's daughter Constance Hines, and family friend Betsy Victoria listen as Cross's daughter Linda Haywood (3L) speaks during a news conference on Capitol Hill April 1, 2009 in Washington, DC. Sen. McCain and Rep.
