WASHINGTON (AP) The government of El Salvador has acknowledged to United Nations investigators that the Trump administration maintains control of the Venezuelan men who were deported from the U.S. to a notorious Salvadoran prison, contradicting public statements by officials in both countries.

The revelation was contained in court filings Monday by lawyers for more than 100 migrants who are seeking to challenge their deportations to El Salvadors mega-prison known as the Terrorism Confinement Center, or CECOT.

The case is among several challenging President Donald Trumps immigration crackdown.

In this context, the jurisdiction and legal responsibility for these persons lie exclusively with the competent foreign authorities, Salvadoran officials wrote in response to queries from the unit of the U.N. Office of the High Commissioner for Human Rights. The U.N. group has been looking into the fate of the men who were sent to El Salvador from the United States in mid-March, even after a U.S. judge had ordered the planes that were carrying them to be turned around.

The Trump administration has argued that it is powerless to return the men, noting that they are beyond the reach of U.S. courts and no longer have access to due process rights or other U.S. constitutional guarantees.

But lawyers for the migrants said the U.N. report shows otherwise.

El Salvador has confirmed what we and everyone else understood: it is the United States that controls what happens to the Venezuelans languishing at CECOT. Remarkably the U.S. government didnt provide this information to us or the court, American Civil Liberties Union lawyer Lee Gelerent said in an email.

Skye Perryman, CEO and president of Democracy Forward, said the documents show that the administration has not been honest with the court or the American people. The ACLU and Democracy Forward are both representing the migrants.

The administration in March agreed to pay $6 million for El Salvador to house 300 migrants. The deal sparked immediate controversy when Trump invoked an 18th century wartime law, the Alien Enemies Act, to quickly remove men it has accused of being members of the Venezuelan gang Tren de Aragua.

In a related case, the administration mistakenly sent Kilmar Abrego Garcia to the same prison, despite a judges order prohibiting the Maryland man from being sent to El Salvador.

The administration initially resisted court orders to bring him back to the U.S., saying he was no longer in American custody. Eventually, Abrego Garcia was returned to the U.S., where he now faces criminal charges of human smuggling while legal battles continue.

Last month, a coalition of immigrant rights groups sued to invalidate the prison deal with El Salvador, arguing that the arrangement to move migrant detainees outside the reach of U.S. courts violates the Constitution.

华盛顿（美联社）——萨尔瓦多政府已向联合国调查人员承认，特朗普政府仍控制着从美国驱逐出境并关押在萨尔瓦多臭名昭著监狱中的委内瑞拉男子，这与两国官员的公开声明相矛盾。

本周一，代表100多名移民的律师向法院提交的文件披露了这一消息。这些移民正试图对将他们驱逐至萨尔瓦多超级监狱——即所谓的“恐怖分子关押中心”（CECOT）——的决定提出质疑。

该案件是对唐纳德·特朗普总统移民强硬政策的数项挑战之一。

萨尔瓦多官员在回复联合国人权事务高级专员办事处下属机构的质询时表示："在此情况下，对这些人员的管辖权和法律责任完全属于相关外国当局。"联合国工作组一直在调查这些人的命运——他们于三月中旬从美国被遣送至萨尔瓦多，尽管当时美国法官已下令载有他们的飞机返航。

特朗普政府辩称其无力遣返这些人，并指出他们已脱离美国法院的管辖范围，无法再享有正当程序权利或其他美国宪法保障。

但移民律师表示，联合国报告所呈现的事实恰恰相反。

美国公民自由联盟律师李·格勒伦特（Lee Gelerent）在邮件中表示："萨尔瓦多证实了我们和所有人的认知——滞留在CECOT的委内瑞拉人的命运实际由美国掌控。值得注意的是，美国政府此前并未向我们或法院提供这一信息。"

民主前进组织首席执行官兼主席斯凯·佩里曼表示，这些文件表明“政府并未对法院或美国民众坦诚相待”。美国公民自由联盟（ACLU）与民主前进组织目前共同为移民群体提供法律代理。

美国政府于3月同意支付600万美元，让萨尔瓦多收容300名移民。当特朗普援引18世纪的战时法律《外敌法案》，以迅速驱逐被指控为委内瑞拉黑帮“阿拉瓜列车”成员的男子时，该协议立即引发争议。

在另一起相关案件中，尽管法官已下令禁止将这名马里兰州男子遣送至萨尔瓦多，但政府仍错误地将基尔马尔·阿布雷戈·加西亚（Kilmar Abrego Garcia）关押至同一监狱。

美国政府最初拒绝执行法院将其引渡回美国的命令，声称他已不在美方羁押之下。最终，阿布雷戈·加西亚（Abrego Garcia）被遣返美国，目前因涉嫌人口走私面临刑事指控，相关法律诉讼仍在进行中。

上月，多个移民权益组织联合提起诉讼，要求废除与萨尔瓦多达成的监狱协议。这些组织认为，该协议将移民拘留者转移至美国司法管辖范围之外的做法涉嫌违宪。
