WASHINGTON — Attorney General William Barr defended the aggressive federal law enforcement response to civil unrest in America as he testified for the first time before the House Judiciary Committee, pushing back against angry, skeptical Democrats who said President Donald Trump’s administration is unconstitutionally suppressing dissent.

The hearing highlighted the wide election-year gulf between the two parties on police brutality and systemic racism in law enforcement..

But Barr said “violent rioters and anarchists have hijacked legitimate protests” and argued the violence taking place in Portland, Oregon, and other cities is disconnected from Floyd’s killing, which he called a “horrible” event that prompted a necessary national reckoning on the relationship between the Black community and law enforcement. But he also said there was no systemic racism in law enforcement.
