TUCSON, Ariz. (CBSNewYork/AP) -- Donald Trump says that he will act presidential if he is elected president, but that the job requires someone who is willing to fight.

Speaking Saturday at a campaign rally in Tucson, Arizona, the billionaire businessman said he promised his daughter and wife that he would act more presidential.

"My wife and my daughter Ivanka said to me, 'act presidential, act presidential.' Like in the last debate, I acted presidential," he told the crowd. "I didn't hit little Marco and I didn't hit lying, lying, lying Ted."

But he immediately shifted gears, pointing to former Republican presidential nominee Mitt Romney as a "stiff'' and vowed to be tough if he is elected president.

He then declared to the audience that he has fallen "in love'' with a Latino woman who he called up on stage because she was holding a sign declaring that Latinos are with Trump.

A number of protesters interrupted his campaign speech at the rally. At first he dismissed them, and then he kicked them out.

He called one protester, who wore the Klu Klux Klan hood, "disgusting.'' Another group, carrying a "Black Lives Matter'' sign were kicked out.

Earlier Saturday, protesters blocked a main highway leading to Trump's rally in a Phoenix suburb and in New York City, several hundred protesters gathered in Columbus Circle for an anti-Trump rally.
