The Trump administration has not been subtle about its intentions. A White House official, speaking anonymously to the Free Press, told the right-leaning media organization that Khalil’s arrest would be a “blueprint” for other actions.

Police, staged inside and outside the Fifth Avenue building before the demonstration, warned protesters to leave or face arrest.
