Warmest Winter in History: More than 20 Cities Break or Tie All-Time Records. The winter of 2014-15 has been so exceptionally and persistently warm across the western third of the United States that more than 20 cities have tied or broken all-time records for the warmest meteorological winter (Dec. 1 through Feb. 28/29) on record.
The Louisiana Purchase occurred during the term of the third President of the United States, Thomas Jefferson, (1757-1826). Before the purchase was finalized, the decision faced Federalist Party opposition; they argued that it was unconstitutional to acquire any territory.
[edit] Negotiation. Jefferson laid the groundwork for the purchase by sending Livingston to Paris in 1801, after discovering the transfer of Louisiana from Spain to France. Livingston was to pursue a purchase of New Orleans, but he was rebuffed by the French. In 1802, Pierre Samuel du Pont de Nemours was enlisted to help negotiate.
