Hillary Clinton took aim at Donald Trump in Delaware Monday, saying the Republican front-runner should come out of his towers and “actually talk and listen to people.”

Before more than 800 people at a Wilmington theater, Clinton did not mention her Democratic rival — Bernie Sanders — and focused instead on Trump and the Republicans. She noted contrasts on climate change, minimum wage and abortion rights. In some of her toughest comments, she suggested Trump was out of touch with average Americans.

“If you want to be president with the United States, you’ve got to get familiar with the United States,” Clinton said. “Don’t just fly that big jet in and land it and go make a big speech and insult everybody you can think of.”

Clinton did not mention Sanders, even when she spoke about gun laws, an area where she frequently attacks his record.

Clinton is campaigning on the East Coast in advance of primary elections Tuesday in Rhode Island, Connecticut, Maryland, Delaware and Pennsylvania.
