The democratic presidential candidate who lost to Nixon in 1972, George McGovern, died Sunday, the Washington Post reported.
McGovern died at the age of 90 in a hospice in Sioux Falls, S.D. The cause of death has not yet been disclosed, the Washington Post reported.
According to the New York Times, President Obama called McGovern "a champion of peace," insisting on a progressive government that would protect the vulnerable and fighting for liberal values throughout his life.
McGovern was the son of a minister and supported civil rights while opposing the Vietnam War, both of which contributed to his loss against Nixon, the Washington Post reported.
