Ocasio-Cortez faces test of her political power

Rep. Alexandria Ocasio-Cortez (D-N.Y.) faces a test of her political influence after endorsing a progressive candidate in the New York City mayoral race. 

Ocasio-Cortez backed New York state Assembly member Zohran Mamdani on Thursday, pitching him as the best chance to upset former New York Gov. Andrew Cuomo, the front-runner since before he entered the race. 

Her endorsement is sure to raise progressive hopes and give Mamdani a much-needed boost ahead of the June 24 primary.
