He is better known for being one of the Founding Fathers of America and the principal author of the 1776 Declaration of Independence.
He also oversaw acquisition of the vast Louisiana Territory from France in 1803 and sent out the Lewis and Clark Expedition, which lasted from 1804 to 1806. He later sent three other explorers to explore the new west. Jefferson doubled the size of the United States during his presidency as well.
Behind the Scenes
- In-universe: Jefferson is still acknowledged, albeit not mentioned or discussed in Olympus Has Fallen. He is shown in one of the White House's many bedrooms while some of Kang Yeonsak's terrorists, led by Yu, are searching for Connor Asher, who has just been safely rescued by Mike Banning.
