"We expect all participants to seek to de-escalate any potential confrontation with those who disagree with our values and to act lawfully at these events..."

On June 14, traditionally Flag Day, protestors plan to gather for a “nationwide day of defiance," according to their website.

Yesterday, according to estimates by event organizers, millions marched in protest against the Trump administration, including its recent controversial immigration-enforcement raids. Hundreds of “No Kings” demonstrations took place in cities and towns throughout the U.

Despite peaceful demonstrations reported in multiple cities, violence flared at some anti-Trump protests over the weekend.
