Vice President Kamala Harris is expected to meet Friday with a group of Arab American and Muslim leaders in Flint, Michigan, according to three sources familiar with her plans, but frustration over the Harris campaign’s outreach efforts is boiling over amid Israel’s recent escalations in Lebanon.

Political commentator Ameshia Cross warned that Vice President Harris is facing warning signs among Arab and Muslim communities, especially in Michigan.

The meeting, which took place backstage, came as Vice President Kamala Harris’s campaign ramped up efforts to appeal directly to Arab and Muslim voters in the final weeks before the election.
