Vice President Kamala Harris gave the public its first real look into her nascent presidential campaign with a stop at her organization’s headquarters in Wilmington, Delaware on Monday night.

Harris’ first applause line came when she discussed her background as California attorney general and as a courtroom prosecutor.

“In those roles, I took on perpetrators of all kinds,” she said, earning cackles while she beamed, clearly enjoying the joke. “Predators who abused women. Fraudsters who ripped off consumers. Cheaters who broke the rules for their own gain. So hear me when I say, I know Donald Trump’s type.”
