"(Yates) has betrayed the Department of Justice," the White House statement said.
Dana Boente, US attorney for the Eastern District of Virginia, the White House said, and was sworn in at 9 p.m. ET, per an administration official. A few hours later, Boente issued a statement rescinding Yates' order, instructing DOJ lawyers to "defend the lawful orders of our President."
Trump didn't call Yates to dismiss her, she was informed by hand-delivered letter, according to a different administration official.
The dramatic move came soon after CNN reported Yates told Justice Department lawyers not to make legal arguments defending Trump's executive order on immigration and refugees.
