“I know predators and we have a predator living in the White House," Harris said to applause during a picnic in West Des Moines. 

"Donald Trump has predatory nature and predatory instincts," she continued. "The thing about predators is that they prey on the vulnerable. They prey on those who they do not believe are strong. The thing about predators you must importantly know [is] predators are cowards."  

Harris made a similar comment last month when she told an audience at the NAACP in South Carolina that she knew how to take on predators as a result of her career as a prosecutor. 

The senator has seen newfound media attention and a boost in the polls since her debate performance in Miami last week.
