Judge James Boasberg’s refusal on Monday morning to lift his injunction barring President Trump’s use of the Alien Enemies Act to deport Venezuelans throws into sharp relief the development of a new strategy — disqualify the judges blocking the administration’s agenda.  

The latest petition to remove a judge from a case argues that a United States district judge of the District of Columbia, Judge Beryl Howell, ruled that parts of Mr. Trump’s executive order penalizing the Perkins Coie law firm were so unlawful as to send “little chills” down her spine. She reckoned that the order’s terms amounted to “pretty extraordinary power for the president to exercise.”
