Mayor Carmen Yulín Cruz of San Juan, Puerto Rico’s capital city, officially announced she’s running for governor in the 2020 elections.

Cruz, who became a prominent adversary of President Donald Trump amid failures in the federal response to the devastating Hurricane Maria, made the long-awaited announcement Friday afternoon at the Caguas Botanical Garden.

“I’ve been thinking for a long time, what’s the best way I can serve Puerto Rico … I’m going to do so by becoming the next governor,” said Cruz, while wearing a white pantsuit with a T-shirt that read “¡Sin Miedo!” — Spanish for “without fear.”

Cruz began her speech talking about her great-grandfather, who was an agricultural laborer, and the ripple effects slavery left behind in Puerto Rico.

“We have to break away from the chains that tie us down in order to have a promising future and break our cycle of poverty,” she said in Spanish.

The announcement came on a Puerto Rican holiday that commemorates the day slavery was abolished there.

Cruz gained national and international attention when she criticized the Trump administration’s hurricane response in Puerto Rico.

“This is personal. The president came and threw paper towels at us,” she told NBC News in a previous interview. “He continues to disregard the pain of people from Puerto Rico.”

While announcing her candidacy, she reminded attendees that the administration of Gov. Ricardo Rosselló “was unable to count deaths after Hurricane Maria” and “stood by Trump when he threw paper towels at people [in Puerto Rico].”

During her speech, she voiced her position on some of the most hot-button issues in the island, such as repealing the century-old Jones Act, which raises the cost of imported goods by limiting foreign ships from going there, and eliminating the federal Financial Oversight and Management Board for Puerto Rico, or the FOMBPR, that oversees the island’s finances. She also called for the island’s $72 billion public debt to be audited.

Puerto Rico’s territorial status is directly linked to the island’s political party system.
