Lawyers for the Trump administration and immigrants are sparring in court over whether President Donald Trump can use an 18th century wartime act against a Venezuelan gang.

Migrants subject to removal from the U.S. under the contested Alien Enemies Act are getting only about 12 hours to decide if they want to contest their removal, according to court documents unsealed Wednesday.

President Donald Trump has invoked a rarely used 1798 law that gives a president immense powers to arrest and deport noncitizens in a time of war.

President Donald Trump’s invocation of an 18th-century wartime law to deport hundreds of immigrants, most of them Venezuelans, to a prison in El Salvador has led to a showdown with the judiciary.

The Trump administration has transferred hundreds of immigrants to El Salvador even as a federal judge issued an order temporarily barring the deportations under an 18th century wartime declaration targeting Venezuelan gang members.

The Supreme Court has allowed the Trump administration to use a 1798 wartime law, the Alien Enemies Act, to deport Venezuelan migrants it accuses of being gang members, ending the temporary halt on deportations ordered by a federal district judge.

A federal judge has ruled against immigration and civil rights advocates attempting to help migrants who had been sent to the Guantanamo Bay military base and trying to prevent further transfers.

U.S. immigration and military authorities say that immigrants from 27 countries were being held at Guantanamo Bay Naval Station in Cuba, while revealing new details of conditions of confinement and defending the government’s authority to transfer and hold immigrants to the military base.

Civil rights attorneys are suing the Trump administration to prevent it from transferring 10 migrants detained in the U.S. to Guantanamo Bay, Cuba.

Civil rights attorneys have sued the Trump administration to gain access to detained migrants who they say have been flown to Guantanamo Bay and held there without being able to consult lawyers or speak to relatives.

The U.S. government has withdrawn from settlement negotiations to end lawsuits filed on behalf of parents and children who were forcibly separated under the Trump administration’s zero-tolerance border policy.

Migrants whose children were taken from them under former President Donald Trump’s zero-tolerance border policy have not reached a settlement agreement with the U.S. government.

A court-appointed committee has yet to find the parents of 628 children separated at the border early in the Trump administration. The committee has found other family members for 168 of the 628 children whose parents have yet to be located. The search committee said it is too early to know how useful the additional phone numbers will be in finding more parents. The ACLU wants Biden to allow separated families to return to the United States to be given “some kind of legal status,” Gelernt said. "We will find the families but we cannot provide the families with the right to return to the United States and give legal status.
