US President Donald Trump arrives on the "Freedom250 train" on his way to attend the grand opening of the Theodore Roosevelt Presidential Library in Medora, North Dakota, July 1, 2026.

US President Donald Trump lashed out Friday at what he called a fresh threat against the country’s identity, taking aim at domestic “radicals and extremists” on the eve of America’s 250th birthday.

In a speech dripping with patriotism, Trump lauded American exceptionalism and praised its past leaders, speaking at Mount Rushmore with its giant carved heads of four of his legendary predecessors.

But he added at the foot of the iconic monument: “As we approach this magnificent anniversary, we see our American identity under a renewed attack.”

He charged that there was “a resurgence of the communist menace in our land.”
