Business related organizations financially supported Charlie Kirk's Turning Point USA for years

The assassination of conservative activist Charlie Kirk in Utah last week has prompted a surge of attention to the nonprofit organization he launched more than a decade ago to facilitate debate that advances conservative ideas on college campuses.

Kirk launched Turning Point USA (TPUSA) in 2012 rather than attend college after the 18-year-old received encouragement from Tea Party activist Bill Montgomery. Later that year, Kirk met Republican donor Foster Friess, who helped finance the nascent political organizing group.

Following Kirk's assassination at the age of 31, TPUSA remains as a key part of his legacy and the group has seen a dramatic rise in interest. Andrew Kolvet, a spokesman for TPUSA and an executive producer of "The Charlie Kirk Show," said the group has received over 37,000 inquiries from people wanting to start new campus chapters, as it currently has 900 official college chapters and about 1,200 high school chapters.

Here's a look at some notable donors to Turning Point USA in the years since Kirk created the group.
