Harris campaign expected to announce running mate Tuesday morning

Vice President Kamala Harris' campaign is expected to officially announce her running mate sometime Tuesday morning, followed by a campaign video that will be released before their Philadelphia rally the same day, according to multiple people familiar with the selection process. 

Politico first reported the campaign's plans.

Harris' expected announcement will come about two weeks after President Biden ended his reelection campaign, prompting the Democratic Party to quickly coalesce around the vice president.
