According to a December 31, 2013 filing with the Federal Election Commission, Yelp is set to open its own political action committee, or PAC. The PAC will allow the popular reviews site to collect money and distribute it to legislators as a way to influence policy.
In November, Yelp hired its first lobbyist, Laurent Crenshaw. In his official lobbying registration form filed in November 2013, the former House staffer said that he was interested in working on patent and copyright reform bills along with a potential federal-level anti-defamation (anti-SLAPP) bill.
