HELENA, Mont. (AP) Former President Bill CLinton will return to Montana on Saturday to campaign for his wife in Bozeman, Lewistown and Miles City.

The trip will be Clinton's fourth this year.

Presidential hopefuls Hillary Clinton and Barack Obama are battling for the state, which will hold the nation's last primary on June 3.

Hillary Clinton has been under increasing pressure to exit the race and allow Democrats to rally behind Sen. Barack Obama, who has the lead in terms of both pledged delegates and superdelegates. At stake in Montana's primary are 16 delegates to the Democratic national convention.

Hillary Clinton's campaign did not release the times or specific locations of Saturday's events.
