Jefferson's main concern regarding the Louisiana purchase was that he was not sure the Constitution gave the president the right to purchase land.
Jefferson was decided to buy the Louisiana territory and sent James Madison to France to help Robert Livingstone -Minister to France- with the negotiations. The result was a successful one. The United States accepted to pay $11,2500,000 for 828,000 square miles of the Louisiana territory. The agreement was signed on May 2, 1803.
