Fifteen US mayors have addressed a letter to Attorney General William Barr and Acting Secretary of the Department of Homeland Security Chad Wolf opposing the use of federal federal law enforcement with "no oversight" against protesters. The letter is calling the act of deploying federal forces against protesters an "abuse of power" and is demanding the withdrawal of "extraordinary federal law enforcement and military presence" from Portland and other American cities.
"These are tactics we expect from authoritarian regimes -- not our democracy [...] The murder of George Floyd in Minneapolis sparked a national uprising and reckoning. The majority of the protests have been peaceful and aimed at improving our communities. Where this is not the case, it still does not justify the use of federal forces. Unilaterally deploying these paramilitary-type forces into our cities is wholly inconsistent with our system of democracy and our most basic values," the letter, posted by Mayor Muriel Bowser, said.
The list of mayors who signed the letter is as follows: Jenny A. Durkan, Seattle; Ted Wheeler, Portland; Keisha Lance Bottoms, Atlanta; Lori Lightfoot, Chicago; Muriel Bowser, Washington DC; Quinton D. Lucas, Kansas City; Martin J. Walsh, Boston; Jim Kenny, Philadelphia; Michael Hancock, Denver; Eric Garcetti, Los Angeles; Sam Liccardo, San Jose; Libby Schaaf, Oakland; Regina Romera, Tucson; Darrell Steinberg, Sacramento; Kate Gallego, Phoenix.
Portland officials had previously stated that federal officers were working in coordination with local law enforcement but have since come out saying that "coordination was not made with Portland police" as the "federal police have their marching order."
According to Chad Wolf, federal law enforcement had only been deployed to Portland. On Monday, Trump vowed to send federal officers to other cities.

Los Angeles Mayor Garcetti announced free Covid-19 testing for every LA resident – whether they show symptoms or not. He stated that "Los Angeles will become the first major city in America to offer wide-scale testing to all of our residents, with or without symptoms". Residents can sign up online to get tested. Test capacities are being increased to handle the expected surge. LA residents can also get tested multiple times in a row, but the mayor's office advised against getting tested daily.
