Answer
An estimated 500,000 people marched in the streets of San Juan on July 17, 2019, to protest the governorship of Ricardo Rosselló. This was the largest protest in Puerto Rico's history, and it came after weeks of public outrage over Rosselló's handling of Hurricane Maria and his administration's corruption. The protesters demanded Rosselló's resignation, and he eventually agreed to step down on July 24, 2019.
