The Huffington Post reports:



George McGovern, who became a leader of the Democrats' liberal wing during his three decades in Congress, lost his 1972 challenge to Nixon, who later resigned amid the Watergate scandal. McGovern has turned his focus in recent years to world hunger.

It was after a lecture tour last October that he was treated for exhaustion. Two months later, he fell and hit his head just before a scheduled interview with C-SPAN for a program focusing on failed presidential candidates who've had a lasting impact on American politics.

McGovern also spent several days in a Florida hospital in April for tests to determine why he occasionally passed out and had difficulty speaking.
