SALEM, Ore. (AP) — Portland’s police chief has resigned, just six months into her job, amid criticism of her department’s handling of protests in Oregon’s largest city. An African American lieutenant on the force replaced her. The shakeup comes as police have been sharply criticized for using what some people called inappropriate force against some protesters. New Police Chief Chuck Lovell said at a press conference that his appointment was completely unexpected and he’s going to care about the community. Demonstrators held two peaceful George Floyd protests in Portland but a third one that lasted until the early hours of Monday resulted in at least 20 arrests, police using tear gas and firing sponge-tipped projectiles.
