Answer:
In completing the Louisiana Purchase, Jefferson had to put aside his principles because this type of transaction was not expressly mentioned in the Constitution. Had he waited for a constitutional amendment, however, the deal might have fallen through. With the support of the American people, Jefferson decided to go through with the purchase.
Jefferson needed to move quickly when he discovered that Spain had signed a secret treaty with France in 1801 ceding Louisiana to France. France suddenly posed a potential threat to America. The fear was that if America did not purchase New Orleans from France, it could lead to war.
The change of ownership from Spain to France resulted in the closure of the port's warehouses to Americans, and it was feared that France would move to cut off America's access to the port entirely. Jefferson sent envoys to France to try to secure the purchase of New Orleans. Instead, they returned with an agreement to buy the entire Louisiana Territory as Napoleon needed money for the impending war against England.
