On Saturday, Sen. Bernie Sanders (I-Vt.) is due to hold his first rally since his heart attack earlier this month and hes planning to make it a big one.

Sanders, 78, had a strong debate performance on Tuesday, trying to put to rest any lingering doubts about whether hes fit enough to be president. And this past week, he rolled out the endorsement of Reps. Alexandria Ocasio-Cortez (N.Y.) and Ilhan Omar (Minn.) , two of the Democratic Party s young progressive rising stars.

The Sanders campaign is obviously hoping for a large crowd on Saturday, when Ocasio-Cortez is slated to join the Vermont senator on stage in Queens, New York, to formally endorse his candidacy. And the campaign is hoping to set the senator apart from some of his opponents including other progressives by choosing a location and message that reflect his commitment to affordable housing, the Green New Deal and taming corporate power.

The Bernies Back gathering is slated to take place in Queensbridge Park, which is in the shadow of both the countrys largest public housing development and New Yorks dirtiest power plant. In a nod to his surroundings, Sanders plans to focus his remarks on expanding affordable housing and lifting up racially diverse, poor and working-class communities like those in the neighboring Queensbridge Houses .

Theyre going to ... try to capture the energy of the housing justice movement here, said New York state Sen. Julia Salazar, a Sanders backer who unseated a Brooklyn Democrat in September 2018 on the strength of calls for greater tenant protections.
