Answer:
Jefferson completed the Louisiana purchase even though he feared it was unconstitutional.
Explanation:
Article IV of the Constitution said new states could be added, but made no provision for taking on foreign territories.
Jefferson was concerned that the treaty powers granted to the President in the Constitution did not allow the executive branch to attain land through treaty.
Jefferson argued that a constitutional amendment was needed. ...
This purchase was needed because the President feared that if the America did purchase New Orleans from France it would eventually lead to war.
The initial intent was to only purchase New Orleans, but when the representatives returned they proposed a buy out of the entire Louisiana territory. Napoleon needed money for an impending war with England. The territory was sold to the US for $15.
