Trump admin updates: US military is preparing for possible activation of National Guard in DC

When the Supreme Court earlier this year limited the scope of nationwide injunctions by district judges in the case involving President Donald Trump's executive order to end birthright citizenship, an avenue left open was for courts to seek nationwide class action involving children born to non-citizens.

Now in a ruling issued Thursday, the Maryland federal judge in that original case has certified a class and enjoined the executive order from taking effect while the question of a constitutional right to birthright citizenship continues to play out in court.

U.S. District Court Judge Deborah Boardman is now the fourth judge to continue to block Trump's executive order seeking to end birthright citizenship.

President Donald Trump announced that he will host a peace summit at the White House on Friday with Azerbaijani President Ilham Aliyev and Armenian Prime Minister Nikol Pashinyan.

Trump said that a peace agreement and bilateral economic agreements between the U.S. and each country will be signed.

"These two Nations have been at War for many years, resulting in the deaths of thousands of people. Many Leaders have tried to end the War, with no success, until now, thanks to 'TRUMP.' My Administration has been engaged with both sides for quite some time," the president wrote in a post on Truth Social on Thursday.

"It will be a Historic Day for Armenia, Azerbaijan, the United States, and, THE WORLD. See you then!" he said.

The Trump administration filed an emergency petition with the Supreme Court Thursday seeking a green light to resume some immigration enforcement tactics in central California that a federal judge had found unlawful.

The judge had concluded that "roving patrols" by DHS, apprehending immigrants solely on the basis of factors like race, accent, the type of work they do and presence at a particular location, violated the Fourth Amendment.

Solicitor General D. John Sauer says the lower court injunction is significantly interfering with federal enforcement responsibilities and must be rolled back.

Sauer also claims that the injunction across central California violates the Court's recent ruling curbing the ability of federal judges to provide relief to non-plaintiffs in a case.

The Supreme Court will likely seek a response from the ACLU respondents before making a decision.
