The correct answer to this open question is the following.
Despite Thomas Jefferson’s goal of limited government, his administration doubled the size of the United States with the purchase of the Louisiana Territory. This led to a dispute between the U.S. and Spain over the borders of the territory.

The territorial differences with the Spanish crown were resolved with the signing of the Adams-Onis Treaty of 1819.
