Thomas Bassford was among those who joined demonstrators at the reenactment of the Battles of Lexington and Concord outside of Boston. “The shot heard ’round the world” on April 19, 1775, heralded the start of the nation’s war for independence from Britain.

The 80-year-old retired mason from Maine said he believed Americans today are under attack from their own government and need to stand up against it.

“This is a very perilous time in America for liberty,” Bassford said, as he attended the event with his partner, daughter, and two grandsons. “I wanted the boys to learn about the origins of this country and that sometimes we have to fight for freedom.”

Elsewhere, protests were planned outside Tesla car dealerships against Trump adviser Elon Musk and his role in downsizing the federal government. Others organized more community-service events, such as food drives, teach-ins, and volunteering at local shelters.

The protests come just two weeks after similar nationwide protests against the Trump administration drew thousands to the streets across the country.

Organizers say they’re protesting what they call Trump’s civil rights violations and constitutional violations, including efforts to deport scores of immigrants and to scale back the federal government by firing thousands of government workers and effectively shutter entire agencies.

Some of the events drew on the spirit of the American Revolutionary War, calling for “no kings” and resistance to tyranny.

Boston resident George Bryant, who was among those protesting in Concord, Massachusetts, said he was concerned Trump was creating a “police state” in America as he held up a sign saying, “Trump fascist regime must go now!”

“He’s defying the courts. He’s kidnapping students. He’s eviscerating the checks and balances,” Bryant said. “This is fascism.”

In Washington, Bob Fasick said he came out to the rally by the White House out of concern about threats to constitutionally protected due process rights, as well as Social Security and other federal safety-net programs.

The Trump administration, among other things, has moved to shutter Social Security Administration field offices.

“I cannot sit still knowing that if I don’t do anything and everybody doesn’t do something to change this, that the world that we collectively are leaving for the little children, for our neighbors is simply not one that I would want to live,” said the 76-year-old retired federal employee from Springfield, Virginia.

In Columbia, South Carolina, several hundred people protested at the statehouse. They held signs that said “Fight Fiercely, Harvard, Fight” and “Save SSA,” in reference to the Social Security Administration.

And in Manhattan, protesters rallied against continued deportations of immigrants as they marched from the New York Public Library north toward Central Park past Trump Tower.

“No fear, no hate, no ICE in our state,” they chanted to the steady beat of drums, referring to the U.S. Immigration and Customs Enforcement.

Marshall Green, who was among the protesters, said he was most concerned that Trump has invoked the wartime Alien Enemies Act of 1798 by claiming the country is at war with Venezuelan gangs linked to the South American nation’s government.

“Congress should be stepping up and saying, ‘No, we are not at war. You cannot use that,’” said the 61-year-old from Morristown, New Jersey. “You cannot deport people without due process, and everyone in this country has the right to due process no matter what.”

Meanwhile Melinda Charles, of Connecticut, said she worried about Trump’s “executive overreach,” citing clashes with the federal courts to Harvard University and other elite colleges.

“We’re supposed to have three equal branches of government and to have the executive branch become so strong,” she said. “I mean, it’s just unbelievable.”
