Portland police close parks, remove barricades to avoid repeat of Seattle-style autonomous zone

Speaking to Fox News Thursday morning, U.S. Customs and Border Protection (CBP) Commissioner Mark Morgan made a distinction, explaining that those wreaking havoc on Portland's streets for six weeks straight "are criminals, those are not protesters."

Acting Homeland Security Secretary Chad Wolf on Thursday released a timeline detailing how over the past few days officers' personal information has been released online and rioters have assaulted law enforcement with hammers, lasers, slingshots and fireworks. Others have been armed with sledgehammers, tasers and "flaming debris."

Meanwhile, a letter penned by four Democratic members of Congress from Oregon – U.S. Sens. Ron Wyden and Jeffrey Merkley and U.S. Reps. Suzanne Bonamici and Earl Blumenauer – said "this politically drive federal response is intolerable," especially after a demonstrator was struck in the head and hospitalized when a federal officer fired less than lethal munition last weekend.
