Vermont Sen. Bernie Sanders will be joined in Denver next Friday by New York Rep. Alexandria Ocasio-Cortez for a stop on the former presidential candidate’s national “Fighting Oligarchy: Where We Go From Here” tour, Sanders’ political organization announced Friday.

The 83-year-old Sanders has been holding packed rallies in swing states, aiming to harness discontent and anger over President Donald Trump and his administration’s moves to fire federal employees, cancel spending, and shutter entire agencies.

The Colorado event is scheduled to take place at 5 p.m. on March 21 at Denver’s Civic Center Park in downtown Denver, with doors set to open at 4 p.m. Sanders’ campaign urged participants to sign up in advance and added that bags, signs and firearms aren’t allowed.

Greeting an overflowing crowd outside a packed gymnasium at a suburban Detroit high school on a recent tour stop, Sanders told supporters that the massive turnout told him that “the people of this country will not allow us to move toward oligarchy,” The Associated Press reported.

“They will not allow Trump to take us into authoritarianism,” Sanders said. “We’re prepared to fight. And we’re going to win.”

It will be the second time Sanders has rallied supporters at the Denver park, which lies between the State Capitol and Denver’s City and County Building, bounded by West 14th Avenue on the south and West Colfax Boulevard on the north.

During his 2020 presidential campaign, Sanders, who is registered as an independent but caucuses with Senate Democrats, drew a crowd estimated at 10,000 to Civic Center Park months before winning Colorado’s presidential primary. Closer to the state’s Super Tuesday election, Sanders drew an even larger crowd — estimated at 12,000 — to an indoor rally at the Colorado Convention Center.
