Schwarzenegger, who took over for Trump this year as host of NBC's "The Apprentice," said it will be the first time since becoming a citizen in 1983 that he will not vote for the GOP nominee. He did not indicate for whom he would vote in November.
The action film star, who did not mention Trump's lewd comments about women, faced criticism over his own alleged sexually aggressive behavior during the 2003 recall election to become California's governor.
At the time, six women who had come into contact with Schwarzenegger on movie sets told the Los Angeles Times that he had touched them in a sexual manner without their consent. The incidents occurred from in the 1970s and '80s, and once in 2000, according to the women.
They described being groped by him in various ways — grabbing their breasts or reaching under the skirt of one. Other stories later followed.
Schwarzenegger's team first denied the claims, but the candidate then apologized, saying he had "behaved badly sometimes."
On Saturday, he did not spell out his reasons for walking away from the candidate of the party he joined after coming to the U..S. in 1968.
"Like many Americans, I've been conflicted this election," Schwarzenegger said. "I want to take a moment to remind my fellow Republicans that it is not only acceptable to choose your country over your party — it is your duty."
