'Please join us!': Bill de Blasio pressures Warren to endorse Sanders

New York City Mayor Bill de Blasio pleaded with Sen. Elizabeth Warren to endorse her former 2020 presidential rival Sen. Bernie Sanders.

“I deeply respect [Warren]. Our nation + our party are better + more progressive because of her leadership. Now our progressive movement needs her more than ever. Senator, if the shoe was on the other foot Bernie Sanders would have endorsed you already. Please join us!” tweeted de Blasio, who ended his own presidential campaign in September, on Tuesday.
