As the United States turns 250 and President Donald Trump prepares to celebrate his 80th birthday, left-wing activists have announced plans for nationwide demonstrations under the “No Kings” movement.

The movement’s website states: “The next 250 starts with us. As America approaches its anniversary about what story we tell. We can let strongman politics and corruption define the moment,” it says. “Or we can make the story of America about people coming together — across race, background, identity, belief, and community — to defend our rights and build a future rooted in people’s power.”

“On June 14, we rise up, we sing out, and we keep organizing,” the group declared.

A 90-minute concert at New York City’s The Town Hall is scheduled to headline the events on that date. The “Rise Up, Sing Out” concert will feature performances by Sasha Allen, Bette Midler, Patti Smith, Rufus Wainwright, actor Jane Fonda, and liberal commentator Joy Reid.

Organizers emphasize nonviolent participation for the activities, which are planned across the United States to coincide with Trump’s birthday.
