Secretary of State Marco Rubio said on Sunday that the US had sent 10 members of the two gangs. This happened in the US, sending the South American-operated MS-13 and Venezuela-based Tren de Lagua to El Salvador late Saturday.
In a social media post, Rubio added that the “alliance” between President Trump and El Salvador's President Naive Buquere “has become an example of the security and prosperity of our hemisphere.”
According to a social media message posted by Salvador's Justice Minister Gustavo Villatero, deportees sent to El Salvador this weekend came from Guantanamo Bay in Cuba. The administration has several detainees there at a US Navy base.
Villatro also posted a video of a man marching from a military plane and being tied up in a prison called the Terrorism Confinement Centre (CECOT).
The Trump administration has sent hundreds of Venezuelans to Salvador's infamous prisons and, at the invitation of Mr Buquere, positioning itself as a key regional ally to Mr Trump, and is scheduled to meet with the Washington president on Monday.
The administration portrays these deportations as violent criminals or terrorists, but court documents show that evidence of government action is often a little less than whether they had tattoos or worn clothing related to criminal organizations.
Mr. Bukere has become Latin America's most popular leader in gang takedowns despite being accused by US prosecutors of halting civil liberties and secretly negotiating with the same gang.
Bukere's spokeswoman Wendy Ramos did not immediately respond to requests for information about the 10 Deporties that Rubio mentioned.
In early February, Rubio announced the possibility of a contract by the Salvador government to convicted criminals with Bukere, who was convicted in the prison system. The administration began sending groups of detainees to El Salvador in mid-March, and so far sent at least five flights to El Salvador carrying Venezuela and Salvador's depositories.
After each flight, the Salvadora government released videos and photos showing the exiles who had arrived at the prison.
According to the administration, some men were expelled from the United States under the wartime power of 1798, alien enemy law, which was the wartime power of 1798.
The Supreme Court ruled last week that the Trump administration could continue to deport Venezuelan immigrants for now using alien enemy laws and overturn a lower court that temporarily suspended those deportations.
The decision represented a victory for the administration, but the decision did not address the constitutionality of using alien enemy laws to send immigrants to prisons in El Salvador. Instead, the judge issued a narrow procedural ruling, saying that the immigration lawyer filed a lawsuit in the wrong court.
In another case, the Supreme Court ordered the administration on Thursday to take steps to return Kilmer Armando Abrego Garcia, a Salvador man who was legally in the United States but was sent to an El Salvador prison in March. However, the administration refused an order for federal judges to handle Abrego Garcia's case and provide a written roadmap for plans to free him, and at Friday's hearing, the judges repeatedly made efforts to get the most basic information about him.
On Saturday, State Department official Michael Kozak told a Maryland judge in Abrego Garcia's case that the detainee is “living” and that he is being held by CECOT, according to the US embassy in San Salvador. The embassy has not responded to requests for information from The New York Times.
Following a Supreme Court order on Thursday, President Trump said the court's ruling showed that the judiciary may not have the power to require administrators to do so, but would follow court instructions if he ordered him to “take someone back.”
On Saturday, Trump wrote about the fortress of true social social society: “These wild bars are currently under the sole custody of El Salvador, a proud and sovereign nation. Their future will be up to President B and his government.”
That day, President Buquere, who posted a photo on social media that showed he was on his way to Washington, has been largely silent about Abrego Garcia's case.
