Jefferson ordered Meriwether Lewis and William Clark to explore the western part of North America. This famous trip became known as The Lewis and Clark Expedition. Like Jefferson, Meriwether Lewis was born in Albemar-le County in Virginia, and served as Jefferson’s trusted White House secretary. When Jefferson discussed the idea of a western expedition, Lewis agreed to take the lead in the matter. Lewis asked Clark, a man whom he met while defending federal interests during the Whiskey Rebellion, to accompany him on the trip.
