Former First Lady Melania Trump presented him with the Presidential Medal of Freedom during President Trump's State of the Union address in the chamber of the U.S. House of Representatives in Washington, DC on Feb. 4, 2020.

Limbaugh launched his popular syndicated radio show in 1988, and quickly became one of the most influential conservative voices in media. He was a staunch and unwavering Trump supporter until the end.

Last year, his show aired on more than 600 stations via Premiere Networks and reached 27 million people weekly.
