Sen. Bernie Sanders (I-Vt.) plans to hold two rallies for Michigan gubernatorial candidate Abdul El-Sayed on Sunday.

The scheduled campaign events provide additional momentum for El-Sayed, a former Detroit health director, following Sanders endorsement on Thursday. The two rallies will be at Cobo Center in Detroit and a location to be determined in Ypsilanti, according to the candidates campaign. Sanders will be joined by Nina Turner, president of Our Revolution, a group that grew out of Sanders 2016 presidential campaign, and Muslim American activist Linda Sarsour.

El-Sayed, a physician proposing state-level single-payer health care and tuition-free college for the vast majority of Michiganders, has consistently trailed former state Senate Democratic Leader Gretchen Whitmer and businessman Shri Thanedar in public polling of the Democratic field.
