The newest effort from the Trump administration to secure the southern border includes authorizing the military to take control of public land along the border.

“The complexity of the current situation requires that our military take a more direct role in securing our southern border than in the recent past,” a White House memorandum said.

The U.S. military will take control of a strip of federal land that spans three states along the southern border in an effort to stem illegal immigration, a memorandum Friday by President Donald Trump said. 

The Trump administration on Saturday confirmed to a federal judge that a Maryland man who was wrongly deported last month remains confined in a notorious prison in El Salvador.

However, the White House filing did not address the judge’s demands that the administration detail the steps it was taking to return Kilmar Abrego García to the United States. The White House only confirmed that García was under the authority of the El Salvador government.

The Supreme Court on Monday allowed the Trump administration to use an 18th century wartime law to deport Venezuelan migrants, but said they must get a court hearing before they are taken from the United States.

In a bitterly divided decision, the court said the administration must give Venezuelans who it claims are gang members “reasonable time” to go to court.

But the conservative majority said the legal challenges must take place in Texas, instead of a Washington courtroom.

The US Supreme Court has cleared the way for President Donald Trump to use a rarely-invoked wartime powers law to rapidly deport alleged gang members - for now.

A lower court had temporarily blocked the deportation of alleged Venezuelan gang members to El Salvador on 15 March, ruling that the actions under the 1798 Alien Enemies Act needed further scrutiny.

Trump has alleged that the migrants were members of the Tren de Aragua gang "conducting irregular warfare" against the US and could therefore be removed under the Act.

The Supreme Court on Monday granted President Donald Trump’s request to vacate a lower court's ruling barring the administration from using a 1798 wartime immigration law to immediately deport Venezuelan nationals – including alleged members of the Tren de Aragua gang – from the U.S., marking a significant victory for the administration as it advances key immigration priorities.

Justices on the high court ruled 5-4 to grant the administration's request to lift the stay, in a temporary victory for Trump and his allies.

On March 24, a shadowy group that calls itself Canary Mission posted a new feature on its website, “Uncovering Foreign Nationals,” in response to President Trump’s recent executive order on combating antisemitism.

The group, which says its mission is to single out those who promote “hatred of the U.S.A., Israel and Jews on North American college campuses,” listed the names of seven students and academics, including three current and former professors at Columbia University.

One of the Venezuelan migrants who is believed to be among the latest group sent to El Salvador on Sunday night was in Guantanamo Bay and had a final order of removal, according to the American Civil Liberties Union (ACLU).

Maiker Espinoza Escalona was the lead plaintiff in one of the Guantanamo cases brought by the ACLU against the Department of Homeland Security filed last month. His partner is currently detained in a detention center in Texas and his two-year-old daughter is in HHS custody, according to the ACLU.

US Homeland Security Secretary Kristi Noem arrived in El Salvador Wednesday to tour the notoriously hellish prison housing alleged gang members deported by the Trump administration — and she’s expected to ask the Central American country’s president to make more room.

Noem, 53, arrived at the Terrorism Confinement Center (CECOT), where 250 suspected Tren de Aragua and MS-13 gang members were shipped from the US by President Trump earlier this month.

Venezuela will resume accepting deportation flights from the US after Venezuelan President Nicholas Maduro suspended the flights earlier this month.

Jorge Rodríguez, the president of Venezuela's Assembly and chief negotiator with the U.S. announced the change in policy on Saturday.

"We have agreed with the U.S. government to resume the repatriation of Venezuelan migrants with an initial flight tomorrow, Sunday," Rodriguez said.
