Senior U.S. administration officials, who previewed the announcement on the condition of anonymity, said ”many dozens” of political prisoners and others considered by the U.S. to be unjustly detained would be released by the end of the Biden administration at noon on Jan. 20.

The U.S. would also ease some economic pressure on Cuba, as well as a 2017 memorandum issued by then-President Donald Trump toughening U.S. posture toward Cuba.

“In taking these steps to bolster the ongoing dialogue between the government of Cuba and the Catholic Church, President Biden is also honoring the wisdom and counsel that has been provided to him by many world leaders, especially in Latin America, who have encouraged him to take these actions, on how best to advance the human rights of the Cuban people,” White House press secretary Karine Jean-Pierre said in a statement.

The Cuban foreign ministry on Tuesday said that the government informed Pope Francis it will release 553 people who had been convicted of different crimes. It said that they will be gradually released, as the authorities analyze the legal and humanitarian ways to make it happen.

The foreign ministry didn’t link the release of the prisoners to the US decision of lifting the designation as a state sponsor of terrorism, but “in the spirit of the Ordinary Jubilee of the year 2025 declared by His Holiness.” In a statement, the foreign minister condemned the ongoing U.S. sanctions on the country as “economic warfare” and acknowledged that the Biden decision could well be reversed by Trump.

The Cuban authorities didn’t say who is among the 553 people who will be released.

The determination by the outgoing one-term Democrat is likely to be reversed as early as next week after Trump, the Republican who is now president-elect, takes office and Secretary of State-designate Marco Rubio assumes the position of America’s top diplomat.

Rubio, whose family left Cuba in the 1950s before the communist revolution that brought Fidel Castro to power, has long been a proponent of sanctions on the communist island. Rubio will appear before the Senate Foreign Relations Committee on Wednesday for his confirmation hearing and is expected to address his Cuban roots in his testimony.

Trump has also appointed Mauricio Claver-Carone, a former White House National Security Council aide and strong supporter of sanctions against Cuba, to be his special envoy to Latin America.

The U.S. officials said the Trump transition team had been informed of the action before it was announced by the Biden White House.

Rep. Mike Waltz, Trump’s pick to serve as national security adviser, previewed a snap back to the previous U.S. policy, but signaled approval for the arrangement.

“Look. anything that they’re doing right now we can do back, and no one should be under any illusion in terms of a change in Cuba policy,” Waltz told Fox News on Tuesday. “We don’t like it, but again, if people are going free, then that’s what it is for now.”

In the final days of Trump’s first administration, on Jan. 11, 2021, the White House reinstated the designation, which had been reversed during the period of rapprochement between Cuba and the United States during President Barack Obama’s second term in office. In doing so, the Trump administration cited Cuba’s support for Venezuela’s leader, Nicolas Maduro, and its refusal to extradite Colombian rebels to Colombia, among other issues, including its continued harboring of wanted Americans.

The move to designate Cuba by Trump was one of several foreign policy moves he made in the final days of his first term.

About six months after Trump designated Cuba as a terror sponsor, the Biden administration levied new sanctions on island officials and the national revolutionary police after hundreds of Cubans were arrested during demonstrations in Havana and other cities to protest shortages, power outages and government policies. They were the first such protests since the 1990s.

Human rights groups and activists, including the U.S. Conference of Catholic Bishops, have been pressing the Biden administration to lift the designation to ease the suffering of Cuban people who feel the impact of Cuba’s economic isolation.

Cuba’s government recognized the announcement and expressed its gratitude, although it deemed it as “limited.”

“Despite its limited scope, this is a decision that points to the right direction and is in line with the sustained and firm demand by the government and the people of Cuba,” the country’s foreign ministry said in a press release.

“The decision announced today by the United States, rectifies, in a very limited way, some aspects of a cruel and unjust policy,” it added.

Congress and the incoming Trump administration will have the opportunity to review and potentially reverse Biden’s actions, though the senior U.S. administration officials said the Biden administration had determined there was “no credible evidence” that Cuba was currently engaged in supporting international terrorism.

The Cuban foreign ministry said that the government is conscious that the incoming government in the U.S. could reverse the decision, but that it will remain “ready to develop a respectful relation with that country, based on dialogue and non-interference in the internal affairs of both countries, despite the differences.”

There was no immediate comment from Rubio or his office, but one of his Republican colleagues on the Senate Foreign Relations Committee, Texas Sen. Ted Cruz, quickly denounced the Biden administration move.

“Today’s decision is unacceptable on its merits,” Cruz said in a statement. “The terrorism advanced by the Cuban regime has not ceased. I will work with President Trump and my colleagues to immediately reverse and limit the damage from the decision.”

Rep. Carlos Gimenez, a Florida Republican, criticized the move and predicted that Trump would quickly reverse Biden’s decision.

“President Biden is a pathetic coward,” Gimenez posted on X. “Come January 20th, there will be a NEW SHERIFF in town & President Trump alongside Secretary of State @SenMarcoRubio will not only put #Cuba BACK on the list but PULVERIZE the regime once & for all!”

Biden in a national security memorandum issued Tuesday certified that Cuba hasn’t provided any support for international terrorism during the last six months and had provided the administration with assurances that it wouldn’t support acts of terrorism in the future.

The move comes after the administration in May removed Cuba from the State Department’s short list of countries that it deems less than fully cooperative against violent groups.
