UNITED STATES–Federal Judge James L. Robart has placed a temporary halt on Trump’s immigration ban on Friday, February 3rd.

President Trump’s disdain for Robart’s block was made evident in his recent tweeting. Trump responded by calling Robart a “so-called judge” and questioning his legitimacy.

Outside of his current halt, Federal Judge Robart’s last controversial instance involved his declaration of “black lives matter” while on the bench in 2015 at a Department of Justice hearing against the Seattle Police department.
