Addressing the challenges Americans face as a nation, Hillary Clinton on Wednesday suggested that Donald Trump’s campaign rhetoric and recent controversial star tweet are further proof that he’s “dangerous” and unfit to serve as president.

During a speech at the Old State House in Springfield, Illinois —the site of Abraham Lincoln’s “House Divided” speech— Clinton argued that from the presumptive Republican presidential nominee’s ban on Muslims to his “promotion of an anti-Semitic image pushed by neo-Nazis,” a Trump presidency would have dangerous repercussions in America and around the globe.

“His campaign is as divisive as any we have seen in our lifetimes,” Clinton said. “It is built on stoking mistrust and pitting American against American. It’s there in everything he says and everything he promises to do as President. And that is why I believe Donald Trump is so dangerous.”

“In times like these, we need a President who can help pull us together, not split us apart,” the presumptive Democratic presidential nominee said.

Last week, Trump came under fire for tweeting an image that was deemed anti-Semitic. A meme tweeted by the presumptive Republican presidential nominee’s account had a montage of Hillary Clinton with a Star of David inscribed and a pile of money in the background. The tweet was soon deleted and reposted, this time with a circle in the star’s place. Trump, speaking at a campaign rally in Ohio last Wednesday, suggested that his campaign shouldn’t have deleted the star meme in the first place because it’s “just a star” and those who think otherwise are “sick people.”
