Live updates: Biden campaign news, Trump shooting investigation and RNC analysis | CNN

Vice President Kamala Harris speaks during a campaign event in Fayetteville, North Carolina, on July 18.

Candidates involved in the 2024 presidential race will hit the campaign trail Saturday after a week of news driven by the Republican National Convention and the growing discord among Democrats over their nominee.

Here’s what’s happening today:

Vice President Kamala Harris is expected to headline a campaign fundraiser in Provincetown, Massachusetts, and deliver remarks.

The state’s Gov. Maura Healey, Democratic Sen. Ed Markey, Transportation Secretary Pete Buttigieg and his husband Chasten Buttigieg will also speak. Actresses Jennifer Coolidge and Adrienne Warren are slated as “special guests.”

Harris is campaigning while President Joe Biden continues his recovery from Covid-19, which has forced him to isolate this week in Rehoboth Beach, Delaware.

All eyes are on the vice president as uncertainty swirls around Biden’s continued candidacy — and as she emerges as the most likely alternative, according to many Democrats.

Meanwhile, the Republican ticket of former President Donald Trump and his vice presidential nominee, Ohio Sen. JD Vance, will be in the battleground state of Michigan for their first joint rally.

The event in Grand Rapids will mark Trump’s first campaign event since the attempted assassination at a Pennsylvania rally one week ago and the subsequent GOP convention. Roads will be closed around the Van Andel Arena and security around the indoor event will be tight, according to local authorities.

Vance has been given a private plane paid for by the Trump campaign — a 737 outfitted with Trump-Vance decals — that will take him to Michigan, according to two sources with direct knowledge.
