McKinney wins Green Party nomination

(CNN) - The liberal environmentalist Green Party nominated former Georgia congresswoman Cynthia McKinney as its presidential candidate Saturday.

The 53-year-old McKinney won five terms in the House of Representatives. She lost to a primary challenger in her suburban Atlanta district in 2002 after she suggested during a radio interview that members of the Bush administration stood to profit from the war that followed the September 11, 2001, terrorist attacks on New York and Washington. Two years later, she made a successful comeback with a low-key campaign in which she largely avoided controversy. But voters ousted her again in 2006, after she drew national headlines with a physical confrontation with a U.S. Capitol Police officer who challenged her after failing to recognize the congresswoman at a security checkpoint.

McKinney held off three other rivals to win the party's nomination during its convention in Chicago. She picked journalist and activist Rosa Clemente as her running mate.
