Vice President Harris’s newly minted presidential campaign announced Sunday morning that it had raised $200 million in less than a week, with two-thirds of that coming from new donors, as Harris seeks to capitalize on what Democrats see as momentum following President Biden’s sudden exit. Harris’s campaign says it has recruited 170,000 new volunteers since last Sunday and is holding 2,300 events to mobilize grass-roots supporters this weekend. Meanwhile, Donald Trump carved out new lines of attack in a reshaped campaign.
