US President Donald Trump kicked off the 250th anniversary celebrations of July 4th with a patriotic speech at Mount Rushmore extolling American culture and warning of a resurgence of the "communist menace."

Axar.az reports, citing CBS News, set against the backdrop of the granite faces of four of his predecessors, Mr. Trump said Friday night that American identity was under attack from communist ideals, taking aim at what he called "radicals" and "extremists" who attack American history.

"There is now a resurgence of the communist menace in our land, including from newcomers to our country who embrace ideas totally opposed to our way of life and our great success. You can be a communist, or you can be a patriot. You cannot be both," the president said.
