What US president loved Fresca so much he had a soda tap installed for the Oval Office?

Fresca is a diet lime and grapefruit citrus soft drink made by The Coca-Cola Company. Borrowing the word Fresca (meaning "fresh") from Spanish, it was first introduced in the United States in 1966.

U.S. President Lyndon B. Johnson, who loved the beverage, had a soda fountain containing Fresca installed in the Oval Office.

In Latin America, Coca-Cola markets a sugar sweetened version of Fresca. In 1997, The Coca-Cola Company responded to requests for this product from immigrant communities by launching it throughout the U.S. as Citra. This was a success but is instead sold as the Citrus flavor in Coca-Cola's Fanta line in areas with large Hispanic populations. In Colombia and Argentina sweetened Fresca is called Quatro and marketed using Fresca's colors and logos.
