• President Trump’s re-election campaign and the Republican National Committee said they had raised $105 million in the second quarter, signaling that the president will have vastly more resources than he did in 2016. Campaign officials said 725,000 individual supporters gave an average donation of $48, marking the first time the R.N.C. attracted a larger share of donations under $200 than its Democratic counterpart.
• Senator Bernie Sanders raised $18 million in three months, a significant sum but less than Pete Buttigieg’s $24.8 million raised in the second quarter. Mr. Sanders’s fund-raising has slowed since he began his campaign, though his second-quarter total is still likely to be among the largest in the field.
• Seeking to overcome a deficit with black voters, Mr. Buttigieg addressed the Rainbow PUSH Coalition, founded by the civil rights leader Jesse Jackson, in Chicago on Tuesday. The convention is a crucial opportunity for Mr. Buttigieg, whose handling of a police shooting last month has disillusioned black voters.
• Senator Cory Booker proposed a sweeping immigration plan aimed at improving the situation on the border, including directing the Department of Homeland Security to phase out any contracts with private prison facilities and county or local prisons over three years.
• Three polls released after the Democratic debates all show essentially the same thing: Support for Kamala Harris is growing, and Joe Biden’s lead is shrinking.
