DENVER — It turns out, people still care about President Donald Trump’s tax returns.

On Saturday, thousands of protesters descended on Denver’s Civic Center Park, demanding he make his most recent tax returns public.

After hearing from a number of speakers that included activists and state lawmakers, they went on a march through downtown Denver.

There were similar protests in cities across the country. Every president and presidential nominee has released their tax returns for the past 40 years.

Trump has said Americans “don’t care at all” about his tax returns, but polls show 74 percent of Americans say he should release them.

Many lawmakers, including some Republicans, have also called on him to make them public. And a petition demanding Trump release his returns has garnered more than 1 million signatures.

Still, the White House has not indicated Trump has any intentions of releasing his returns. So Trump critics are prepared to make some noise.

“We march to demand that the president release his returns, as he has repeatedly promised, but failed, to do,” the Tax March website reads. “We march because it is in the best interest of the American people to know what financial entanglements and conflicts of interest our leaders have.”

The organizers of Saturday’s marches say there are more than 180 planned across 48 states and the District of Columbia. They’re all scheduled to start at various times throughout the day.

Much like the “Pussyhats” symbolized by the Women’s March in January, the hallmark of this protest are giant inflatable chickens.

On Saturday morning, chickens could be spotted on the steps of the Capitol building and outside the Trump Hotel. Thirty-foot inflatable chickens will also go up at the marches in New York and San Francisco, according to Kevin Donohoe, a Tax March organizer.

The inflatable chickens were designed in Hong Kong to celebrate the Year of the Rooster, and they were purposely made to resemble Trump this year.

Organizers for Tax March San Francisco discovered the chicken and redubbed it “Chicken Don” to poke fun at the president for being too afraid to release his tax returns.

Since then it’s spread across the country with dozens of marches purchasing chickens, Donohoe said.
