Smaller protests also broke out across the island over the weekend, though most people were expected to hit the streets on Monday.
The calls to oust the governor have caught the attention in the mainland U.S. and several officials, including presidential candidate Julián Castro, have come out in support of the protesters.
Castro, a Democrat, openly called on Rosselló to step down, saying “it’s clear that Gov. Rosselló can no longer be effective.”
Some well-known athletes with ties to the island also urged the governor to resign last week, including the Los Angeles Dodgers’ Enrique Hernandez and the St. Louis Cardinals’ Yadier Molina.
Puerto Rico’s Center for Investigative Journalism earlier this month published nearly 900 pages of private messages between Rosselló and several other government officials.
In one message Rosselló called one New York female politician of Puerto Rican descent a “w—e” and described another as a “daughter of a b—h.” One chat also made vulgar references to Latin pop star Ricky Martin’s homosexuality.
During a July 11 news conference, Rosselló asked Puerto Ricans to forgive him for the comments he made in private. In further media appearances, he continued to ask for forgiveness over the comments many deemed offensive and misogynistic.
