Harris Campaign Says It Raised $200 Million Since Biden Dropped Out

Vice President Kamala Harris’s campaign said on Sunday that it had raised $200 million in the week since President Biden withdrew from the race — more than Mr. Biden’s haul in the first three months of the year.

Roughly two-thirds of that amount came from first-time donors, according to the campaign, offering another sign that Ms. Harris’s ascent to the top of the party’s ticket has invigorated Democrats. The campaign also said it had signed up more than 170,000 new volunteers.

And Ms. Harris herself said at a fund-raiser on Saturday, “We are the underdogs
