Mt Rushmore is 2 founding fathers.
-George Washington - founding father, first president and leader of the colonial army during our war for independence
-Thomas Jefferson- founding father, 3rd president, and wrote the Declaration of Independence
-Abraham Lincoln - president during the Civil War
-Theodore Roosevelt - president that dismantled monopolies, protected our nation's natural beauty, got us the Panama canal, and implemented the actually good regulations like food safety. Pretty much one of the most memorable presidents that worked to enhance the country for the betterment of the people and is everything Trump wishes he was.
All 4 were colossally important in the founding and development of our country
