Trump admin live updates: Trump says 'couldn't care less' if automakers raise prices

In a ruling on Monday denying the Trump administration's request to dissolve his previous order blocking the deportations, U.S. District Judge James Boasberg wrote that President Donald Trump's "unprecedented use" of the Alien Enemies Act does not remove the government's responsibility to ensure the men removed could contest their designation as alleged gang members.

"The Court need not resolve the thorny question of whether the judiciary has the authority to assess this claim in the first place. That is because Plaintiffs are likely to succeed on another equally fundamental theory: before they may be deported, they are entitled to individualized hearings to determine whether the Act applies to them at all," Judge Boasberg wrote, adding the men were likely to win their case.

The ruling comes just before the D.C. Circuit Court of Appeal is set to hear arguments as the Trump administration seeks to have Boasberg's block of the law overturned.

A federal appeals court on Monday will hear arguments about President Donald Trump's invocation of the Alien Enemies Act to deport more than 200 Venezuelan migrants alleged to be gang members.

If the D.C. Circuit Court of Appeals overturns a judge's order blocking the use of the centuries-old wartime law, the Trump administration could exercise the authority to deport any suspected migrant gang member with little-to-no due process.

The hearing is set to get underway at 1:30 p.m. Read more about the case here.

President Donald Trump and Louisiana's Republican Gov. Jeff Landry will deliver remarks Monday afternoon in the Roosevelt Room at 2 p.m ET.

Landry, appearing on Newsmax from the White House lawn on Monday morning, praised Trump's executive order to begin dismantling the Department of Education.

At 3 p.m. ET, Trump will participate in a Greek Independence Day celebration in the East Room.

A coalition including the NAACP and the National Education Association, the largest union representing public education professionals, is expected to file suit Monday against the Trump administration over the steps it's taken to dismantle the Department of Education.

Trump signed on Thursday an executive order that aims to gut the department, a promise he made repeatedly on the campaign trail. The order describes the department as supporting an "unaccountable bureaucracy" that has "plainly failed our children, our teachers, and our families."

The following day, Trump announced two key functions of the Department of Education would be moved to new departments. The Small Business Administration will take on student loans, and the Department of Health and Human Services will take on special needs and nutrition efforts.

The coalition, which collectively represents millions of teachers, students and others, are expected to argue in their suit that the administration's actions amount to "a de facto dismantling of the Department by executive fiat."

Dismantling the department would put at risk "millions of vulnerable students, including those from low-income families, English learners, homeless students, rural students and others who depend on Department support," the coalition said. More than 400,000 jobs would be put at risk, they added.

"Nothing is more important than the success of students. America's educators and parents won't be silent as Donald Trump, Elon Musk, and Linda McMahon try to steal opportunities from our students, our families, and our communities to pay for tax cuts for billionaires," NEA President Becky Pringle said in a statement.
