A lengthy protest march opposing President Trump's agenda has been on the march downtown, starting at 555 California Street and making its way down Market to the Castro, before heading down 18th Street to the Mission.

According to a Facebook event, the "Silence Is Violence" protest is opposed to racism, misogyny, and police brutality, and in favor of "trans and queer acceptance, indigenous sovereignty, #NoDAPL, and Black Lives Matter." 

Mentions of the march have been scant on Twitter, but tipster Sarah M. sent some photos of it in progress at Market and Valencia, and the SFMTA has regularly been tweeting updates on its whereabouts.

The protest blocked transit and traffic on Market for approximately an hour after it began at noon, and it's expected to continue until 5pm. As of 2:50pm, it's currently at 18th and Sanchez streets; it will eventually make its way down Mission Street to the Ferry Building.
