MILWAUKEE — A crowd of thousands of fired-up Democrats chanted “Lock him up!” Tuesday at Vice President Kamala Harris’ first rally as the party’s presidential candidate as Harris leaned into her past as a “prosecutor” while bashing Donald Trump.

“I was elected attorney general of the state of California and I was a courtroom prosecutor before then. And in those roles I took on perpetrators of all kinds: 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,” Harris, 59, said to wild applause.
