Vermont Sen. Bernie Sanders is staffing up ahead of another potential run.

Politico reports he is adding staff to his digital operations ahead of a potential 2020 campaign for president.

Citing multiple sources familiar with the campaign, Politico reports the Sanders team is in talks with the film team that created a viral campaign video for Alexandria Ocasio-Cortez, the political newcomer who unseated Democratic Caucus Chair Joe Crowley in New York’s 14th congressional district.

It's time for a New York that works for all of us.



On June 26th, we can make it happen - but only if we have the #CourageToChange.

Additionally, Politico reports, two former members of the Sanders campaign in 2016 have agreed to join again should Sanders announce a 2020 campaign.

Sanders, 77, has not yet announced whether he will run for president again. He mounted a 2016 campaign for the office but the Democratic nomination was secured by former Secretary of State Hillary Rodham Clinton.
