President Donald Trump marked the 250th anniversary of American independence with a speech that began by praising American exceptionalism. The speech took a darker turn, however, as Trump warned of the threat of communism to American liberty.

Details of the speech are available from NBC 5 Dallas-Fort Worth. It is known that Trump delivered the speech from Mount Rushmore, a national park that honors some of America's most prominent presidents. The speech's tone was notable for its departure from the typically unifying speeches given by past presidents on similar occasions.
