A little more than a month after telling South Carolina voters that Bernie Sanders “will do the right thing,” Spike Lee has produced a new campaign ad for the Democratic presidential candidate.

The ad, released Saturday by the Sanders campaign, features a number of activists speaking to the camera about the Vermont senator.

“People of color have a deeply vested interest in what Bernie Sanders brings to us in this election,” singer and activist Harry Belafonte says at the beginning of the ad.

Activists Erica Garner, Shaun King, and Linda Sarsour are also seen in the 30-second spot, which comes ahead of the New York primary on April 19.

In February, Lee endorsed Sanders in a radio ad that played in South Carolina. “He fought for wealth and education equality throughout his whole career,” he said. “No flippin’, no floppin’. Enough talk. Time for action.”
