Abdul El-Sayed, backed by Bernie Sanders, leads polls ahead of Haley Stevens and Mallory McMorrow in primary

Alexandria Ocasio-Cortez has thrown her support behind Abdul El-Sayed, the doctor and progressive Democrat seeking the party's nomination in Michigan's closely watched US Senate race.

In an interview with the New York Times, Ocasio-Cortez - an influential congresswoman on the left of the Democratic party - endorsed El-Sayed, a former public health director. Despite our ideological differences and whatever disagreements there are in the party, every single one of us sees this moment as existential," she said.
