Lt. Gov. Jennifer Carroll abruptly resigned Tuesday amid law enforcement questions about a Florida Internet sweepstakes company at the center of a nationwide criminal investigation.

Key points:

• Florida Department of Law Enforcement interviewed Carroll Monday about her connections to the company, Allied Veterans of the World, a Florida-based non-profit that operates a chain of Internet cafes. Carroll once owned a public relations firm that represented Allied Veterans, and she did work for the company at the same time she served in the Florida House.

• It’s unclear if Carroll is the target of any criminal charges. Attorney General Pam Bondi and law enforcement officials have scheduled a 2:30 p.m. press conference in Orlando to discuss the case. Gov. Rick Scott also has announced an afternoon press conference.
• On Monday, leaders of the company and the head of Jacksonville’s police union were arrested on charges of racketeering and money laundering.
• Allied is a big player in Florida. In 2011, it had 40 locations statewide. Allied has spent hundreds of thousands of dollars on state lobbyists and contributed $25,000 for a Scott/Carroll inauguration event.
