A federal judge temporarily blocked President Trump’s executive order that aims to restrict automatic citizenship to babies born on U.S. soil, calling it “blatantly unconstitutional.” The order Mr. Trump signed on Monday was an effort to upend the nation’s immigration laws and reverse decades of precedent and would affect children born to undocumented or temporary immigrants.

On his first full day in office Tuesday, President Donald Trump continued sweeping actions, including ordering the shuttering of all executive branch diversity, equity, and inclusion offices and ordering all employees working in such offices to be placed on leave.

A judge in Maryland heard arguments over the timing of the president’s order, which is set to go into effect in 30 days.
