Hillary Clinton said Monday the bombings in New York and New Jersey show the threat of terrorism is "real," and that Donald Trump's comments are being used as a terrorist recruiting tool.
Authorities on Monday said they were searching for Ahmad Khan Rahami, a 28-year-old Afghan-born U.S. citizen, as a suspect in the bombings.
On Saturday, a bomb exploded in the New Jersey shore town on Seaside Park, forcing the cancellation of a large charity race. Later in the day, a bombing in New York's Chelsea neighborhood injured 29 people. Officers found a possible secondary device nearby. On Sunday, five additional explosive devices were found near a train station in Elizabeth, New Jersey.
"This threat is real, but so is our resolve," Clinton said at a morning news conference before a planned trip to campaign Philadelphia. "Americans will not cower. We will prevail."
Regarding immigration, Clinton said she is in favor of tough vetting. "We need a better visa system," she added.
"Let's not get distracted by the kind of campaign rhetoric coming off from the other side," the Democratic presidential nominee said.
She criticized her GOP rival's comments as providing fuel for terrorists.
"We know that a lot of the rhetoric we've heard from Donald Trump has been seized on by terrorists, in particular ISIS, because they are looking to make this into a war against Islam," she said.
Clinton held the news conference in White Plains ahead of a planned trip Pennsylvania, an important swing state in the Nov. 8 election.
Clinton will speak at Temple University as she vies for support from a key voting group: millennials. In polls, her support from this group has waned in recent weeks.
