SAN JUAN, Puerto Rico - Puerto Rico Gov. Ricardo Rossello said Sunday evening that he will not resign in the face of public furor over an obscenity-laced leaked online chat, but he will not seek reelection or continue as head of his pro-statehood political party.

Protesters said they were not satisfied by Rossello's concessions, and pledged to continue demonstrations that have filled the streets of Old San Juan for more than a week.

“He's stretching things out. We had hoped he'd taken the decision to resign. He's making the people's pain last longer,” said Emmarie Morales, a protester from southeast coastal town of Patillas. She said the governor's decision would not end the protests. “He's given us more strength to protest. We aren't going to sit around watching Netflix.”

In a brief video posted on Facebook, Rossello also said he looked forward to defending himself against the process of impeachment, whose initial stages are being explored by Puerto Rico's legislature.

“In spite of everything, I recognize that apologizing isn't enough, that only my work will help restore confidence ...,” the governor said. “Facing that scenario, I announce to you that I will not seek reelection next year.”

The 889 pages of chat on the encrypted app Telegram between the governor and 11 close allies and members of his administration, all men, showed the governor and his close advisers insulting women and mocking constituents, including the victims of Hurricane Maria.

Just hours after Rossello spoke, another top official submitted his resignation from the government.

“Unfortunately the events in recent weeks, including the attitudes reflected in the comments of officials and advisers of the current administration, do not match my values ??and principles,” wrote Gerardo Portela, who has been principal investment officer, president of Puerto Rico's Economic Development Bank and executive director of the Housing Finance Authority.

Since the chat leaked on July 13, hundreds of thousands of outraged Puerto Ricans have marched to Rossello's official residence in the largest protest movement on the island since Puerto Ricans successfully demonstrated to demand an end to U.S. Navy military training on the island of Vieques more than 15 years ago.

Puerto Rico's justice secretary, Wanda Vazquez, would assume the governor's role under the territorial constitution's line of succession if Rossello should quit.

The upheaval comes as the U.S. territory is struggling to recover from Hurricane Maria and trying to restructure part of $70 billion in debt amid a 13-year recession in this territory more than 3 million American citizens who do not have full representation in Congress or a vote for president.

“Today, I have the great responsibility to direct my efforts, and those of my administration, to keep searching for ways and means for us, united before God, to be able to keep guiding our island,” the governor said.

But anger grew across the island after his message. A group of legislators and mayors from Rossello's party remained stuck inside a community centre in the upscale city of Guaynabo late Sunday as protesters arrived to demand that the governor resign. The politicians had met earlier with the Rossellor, who managed to leave with his bodyguards before the others became trapped.

On Monday morning, tens of thousands of Puerto Ricans were expected to take over one of the island's main highways to demand Rossello's resignation as legislators considered whether to take the first steps of the impeachment process.

Arriving late Sunday to prepare for Monday's march was Nicole Quintana, a 32-year-old dentist, along with her husband and their 3-month-old son.

“We had to do it for him,” she said, gesturing to her son. She said they drove about two hours from the coastal town of Isabela to participate. “Finally people have said: 'Enough is enough. This ends here.”'

Pressure on Rossello to step down has grown throughout the week as the chorus calling for his resignation grew to include Puerto Rico music superstars Ricky Martin, Bad Bunny and Residente and a string of U.S. politicians including Congress members from both parties, several Democratic presidential candidates and Puerto Rico's non-voting representative in Congress.

Rossello was elected governor in November 2016 with nearly 50% of the vote, and he had already announced his intention to seek a second term. A graduate of MIT with a doctorate in genetics, he is the son of former Puerto Rico Gov. Pedro Rossello, who flew to the island to marshal support after the chat was made public.

The governor belongs to the New Progressive Party, which seeks statehood for the island, and he is also a Democrat. Most of his time has been spent seeking federal funds since Hurricane Maria devastated the island on Sept. 20, 2017, and battling austerity measures implemented by a federal control board that Congress set up to oversee the island government's finances.

The upheaval against Rossello prompted at least four cruise ships to cancel visits to Puerto Rico, and many officials worry about the impact a resignation would have on the already fragile economy as the island rebuilds from Maria, a Category 4 storm that caused more than an estimated $100 billion in damage.

Another concern is the recent string of arrests involving federal corruption charges targeting Puerto Rico officials, among them two former agency heads, including former education secretary Julia Keleher.
