The Department of Homeland of Security will begin partially implementing President Trump's immigration executive order on Thursday, days after the Supreme Court reversed two lower court rulings that had completely blocked implementation.

DHS spokesman David Lapan told the Washington Examiner implementation will "begin tomorrow and we'll release additional information then."

Lapan added that DHS will continue to "work with the Departments of State and Justice on the way forward for implementation of the executive order based on the Supreme Court's ruling."

The Supreme Court on Monday lifted most of the lower-court injunctions against Trump's executive order, which will temporarily ban travel to the United States from six Muslim-majority countries for foreign nationals who lack any "bona fide relationship with any person or entity in the United States."

The Supreme Court also announced it will hear oral arguments on the case in its October term.

With that decision, the court disregarded lower court rulings that said the order was aimed at excluding people because of their religion, and that the White House didn't offer enough justification for the order.

Three Supreme Court justices also went further by arguing that the court should have immediately allowed the entire order to take effect.

"I agree with the court that the preliminary injunctions entered in these cases should be stayed, although I would stay them in full," Justice Clarence Thomas wrote in a dissent that was joined by Justices Samuel Alito and Neil Gorsuch. "The decision whether to stay the injunctions is committed to our discretion ... but our discretion must be 'guided by sound legal principles'."
