President Trump kicks off America’s 250th birthday weekend with a speech at Mount Rushmore in Keystone, South Dakota, describing communism as a major threat to the United States. Multiple outlets report that Trump frames communism as incompatible with American liberty and the Constitution and warns that the country could see a resurgence of the ideology. In the remarks, he characterizes communism as the “enemy of July 4, 1776” and says it poses a “mortal threat” to free people, linking it to major historical conflicts such as World War I and World War II and events including Pearl Harbor and 9/11.

Several sources also describe the speech as unusually partisan for a July 4 kickoff tied to national commemoration. Trump uses the address to argue that supporters of communism and Marxism are attacking American heritage and history, and he presents the ideology as “godless,” associating it with tyranny, control, and violence.

Beyond the speech’s warnings, one report says Trump uses the event to promote legislative priorities ahead of upcoming midterm elections, including calling for changes to Senate procedures and urging passage of a proposed measure referred to as the SAVE America Act.
