A US federal judge in Seattle blocked, temporarily, President Donald Trump’s attempt to rescind birthright citizenship—the idea spelled out in the Constitution that every person born in the United States is an American citizen, The Seattle Times reports.

Senior US District Judge John Coughenour on Thursday was blistering in his criticism of Trump’s action as he granted a temporary restraining order that blocks Trump’s executive order from taking effect nationwide.

“I’ve been on the bench for over four decades, I can’t remember another case where the question presented is as clear as this one is. This is a blatantly unconstitutional order,” Coughenour, an appointee of Ronald Reagan, said from the bench. “There are other times in world history where we look back and people of goodwill can say where were the judges, where were the lawyers?”

The aforesaid executive order will remain blocked for at least 14 days while respective lawsuits in Washington and elsewhere proceed.
