Thousands of people flooded the streets of San Juan on Monday, calling for Puerto Rico Gov. Ricardo Rosselló to resign from office. The mass demonstrations are expected to be one of the largest protests ever seen in a U.S. territory.

A scandal that recently exposed chat messages Rosselló sent among his inner circle showed the governor and his allies insulting women, gay people and mocking everyday Puerto Ricans, even victims of Hurricane Maria.

On Sunday, Rosselló announced that he will not step down. Instead, he said he would not seek re-election next year — a move that did little to dampen widespread protests that have now been held for 10 straight days. By noon Monday, demonstrators had already clogged a major highway, causing the island's largest mall to close and prompting cruise stops to cancel port stops to keep tourists away.
