1. Protesting Puerto Ricans paralyzed San Juan.

Filling miles of a major highway, tens of thousands of people demanded that Gov. Ricardo A. Rosselló resign.

Organizers hoped the island-wide strikes and rallies would draw a million people — about a third of Puerto Rico’s population. It appears to be one of the largest protests in the U.S. territory’s history.

Puerto Ricans have suffered through years of economic austerity measures and the devastation of Hurricane Maria, but the last straw was the publication last week of hundreds of pages of a group chat between Mr. Rosselló and aides that included crude, offensive comments — and revealed a cozy relationship between the governor and former staff members now representing special interests.
