Jennifer CarrollFlorida Lieutenant Gov. Jennifer Carroll resigned today after a former client of her PR firm was linked to illegal gambling.

Carroll, a former state legislator and lieutenant governor since 2009, previously ran a PR firm -- 3N & JC -- with her husband, Nolan, which represented the non-profit Internet cafe operator Allied Veterans of the World. A state investigation into the organization -- Carroll was interviewed by authorities on Monday -- led to arrests this week on racketeering and money laundering charges.
