Trump’s executive order, signed in January, seeks to deny citizenship to children who are born to people who are living in the U.S. illegally or temporarily. It is part of the hard-line immigration agenda of the president, who has called birthright citizenship a “magnet for illegal immigration.”

A White House spokesperson told CBS News Los Angeles that the order was a "gross overstep of judicial authority."

The big tax and spending bill President Trump signed into law earlier this month included $75 billion for Immigration and Customs Enforcement, and the Supreme Court recently told the administration it could deport people to countries with which they have no ties.

The International Federation of Professional and Technical Engineers, which represents immigration court judges as well as other professionals, said in a news release that 15 judges were fired “without cause” on Friday and another two on Monday.
