Bernie Sanders, inching closer to a second bid for the White House, has recorded a campaign video in which he says he is running for president in 2020, according to two people familiar with the spot…

Another hint that Sanders is getting closer to a launch: As POLITICO reported this week, the Sanders team has been interviewing people for top staff positions. Chuck Rocha, a political consultant who advised Sanders’ 2016 campaign, is expected to join him again if a second bid materializes.

It is unclear when, or even whether, the Sanders video will be released. It’s possible that Sanders could launch a 2020 campaign with an exploratory committee and then formally declare his candidacy later, a route other presidential candidates, such as Sen. Elizabeth Warren, have taken.
