LOS ANGELES — Vice President Kamala Harris poked at Republican Donald Trump during a fancy fundraiser on Sunday, telling donors that as she campaigns around the country her “crowds are pretty big” — before heading to Nevada for a rally at the same venue where the GOP nominee appeared two weeks ago. During the presidential debate, Harris appeared to get under Trump’s skin when she said people were leaving his rallies early because of his rambling speeches. And she’s kept it up on the campaign trail.

She also has moved into what Trump considers his terrain — immigration — with a Friday visit to the border town of Douglas, Arizona. It was her first trip to the U.S.

-Mexico border since taking over for President Joe Biden atop the Democratic presidential ticket. Harris’ four-day West Coast trip has been crafted with dual purposes: She was opening and closing with stops in Sun Belt battlegrounds — Arizona and Nevada — where the vice president is trying to shore up support as Trump pounds her relentlessly over illegal migration. And her mid-stay in California was devoted to hauling in campaign contributions from donors in her blue home state.

Harris’ border visit in Arizona seemed to irk Trump. The GOP leader has spent two days railing about the vice president during his rallies, upping his personal attacks against her, claiming she was responsible for a border “invasion,” and stirring up unfounded fears that she’d usher in lawlessness if elected.
