Alaska Sen. Mike Gravel, a forceful opponent of the Vietnam War who made history when he read passages from the Pentagon Papers in Congress, died Saturday at his home in California. He was 91. Gravelâs political career spanned the Alaska Legislature and Congress. He also made unsuccessful bids for president. Alaska politicians recalled Sunday the impact Gravel had on politics in Alaska and across the nation. âMike committed his life to his country and to public service through his work with the military, Alaska State Legislature and the U.S. Senate," said Gov. Mike Dunleavy and First Lady Rose Dunleavy, in a prepared statement. "His legacy is of leadership and commitment to fight for Alaskans and Alaska. We offer our sincere condolences to the Gravel family in this time of mourning.â
