Amid reports that Mike Bloomberg could team up with Hillary Clinton by making her his running mate, powerful Clinton ally Capricia Marshall is joining the former New York City mayor’s presidential campaign, Page Six can exclusively reveal.

After the news broke on Saturday that internal polling found that a Bloomberg-Clinton ticket “would be a formidable force” to try to take down President Trump, Bloomberg tweeted, “I would not be where I am today without the talented women around me. I’ve depended on their leadership, their advice and their contributions.”

Now Page Six can reveal that Bloomberg has tapped DC-based Marshall, who was President Bill Clinton’s White House social secretary from 1997 to 2001. Under the Obama administration, she served as chief of protocol of the United States — a sensitive diplomatic position bearing the rank of ambassador — from 2009 to 2013.

Prior to that, Marshall was a special assistant to Hillary when she was first lady in 1993. In 2006, Marshall worked on then-Sen. Hillary Clinton’s re-election and then joined her presidential campaign in 2008. In her role as senior adviser, she led surrogate speakers and helped coordinate women’s outreach. She also appears throughout the new Hulu docuseries about Hillary.

It was not immediately clear what position Marshall would take on the Bloomberg campaign, which now boasts more than 2,100 staffers. But a Democratic source told Page Six, “Capricia Marshall is one of the very top people in Hillary’s immediate inner circle, she is far more than a campaign person, far more than a political aide, and is a very respected insider in the Obama circle.

“Bloomberg has to network into the Democratic establishment in a more serious way, Capricia can help build a greater knowledge and awareness about Mike because she has personal relationships through Hillary with African American leaders, Hispanic leaders and female activists.

“Capricia is very connected to the Democratic political orbit and will give Bloomberg a stronger link to the Dem establishment, and therefore more credibility. She will help convince them Mike is not a quasi-Republican after he heavily backed GOP candidates in the past.

“She will help Mike reach out to women and the African American community, which remains unsatisfied with his apology over his stop-and-frisk policy as New York City mayor.

“Hiring Capricia is a very smart move. She’s a big deal.”

A spokesperson for the Bloomberg campaign didn’t get back to us. Marshall could not be immediately reached.
