The National Thoroughbred Racing Association's political action committee cleared the $3 million mark in total contributions, the organization said Aug. 20.
Horse PAC was formed in 2002 to support bipartisan lobbying on behalf of the Thoroughbred industry.
"Over 500 NTRA members who recognize the importance of a strong industry presence in Washington, D.C., have made this milestone possible," NTRA president and chief executive officer Alex Waldrop said in a release.
Horse PAC supports candidates who serve on congressional committees that oversee livestock and agricultural issues, Internet gaming, taxation, immigration, and the Interstate Horseracing Act; serve in leadership roles; understand horse racing's issues; have racetracks, breeding farms, training centers or advance deposit wagering systems in their states; are members of the Congressional Horse Caucus; or are emerging leaders meriting early support in their legislative careers.
