Sen. Bernie Sanders (I-Vt.) apparently is close to announcing another presidential run.

According to two sources who spoke with Politico, Sanders has recorded an announcement signaling his intention to seek the presidency in 2020. He made an unexpectedly strong bid for the Democratic nomination on 2016, defeating Hillary Clinton ― the frontrunner and eventual nominee ― in several primaries and caucuses.

Politico reported that Sanders’ team had started holding interviews for senior staff jobs, focusing in particular on women and minorities after blowback for a lack of diversity on his team in the 2016 race.

Last month, sources told Yahoo News that Sanders would be launching a campaign soon, and that he would begin with an exploratory committee.

If Sanders announces a run, he would join an increasingly long list of potential nominees for the Democratic nod that include fellow Sens. Amy Klobuchar (Minn.), Elizabeth Warren (Mass.), Cory Booker (N.J.), Kirsten Gillibrand (N.Y.) and Kamala Harris (Calif.), as well as Rep. Tulsi Gabbard (Hawaii) and Obama administration Cabinet member Julián Castro.

Sanders presumably will abandon his political designation as an independent in a second White House quest. The Democratic National Committee changed its rules last year to state that the contenders for the party’s nomination must be registered Democrats.
