GOP candidate Donald Trump held rallies in Washington state on Saturday. As usual they were met with protests and huge crowds.

And while Trump stuck to his regular talking points about building "the wall" and now bashing Massachusetts Sen. Elizabeth Warren, he also took a low blow on his potential Democratic rival, Hillary Clinton.

Trump said Clinton has a "bad temperament," and then in reference to her rocky marriage to President Bill Clinton, he said, "her husband learned that a few times."

Trump is struggling with women voters, along with other demographics. An April Gallup poll showed 7 in 10 women have an unfavorable opinion of him.

Trump was greeted in Washington by supporters and protesters, the latter of whom blocked his motorcade from arriving at a rally in Lynden, King5 reports.

Also on foreign policy, Trump said he opposed the war in Iraq, even though he was not in office, and added "Iraq is Harvard for terrorists. If you want to be a terrorist, you go to Iraq. Iraq is Harvard for terrorists."
