Ms. Carroll, a former Navy lieutenant commander, has not been charged with a crime and it is unclear whether she is being investigated.

Sweepstakes cafes operate in a legal gray zone, allowing customers to buy Internet or phone cards that allow them to play games that resemble slots or video poker. They have been called “convenience casinos.”

Pam Bondi, the Florida attorney general, announced Wednesday that law enforcement officials had issued nearly 60 arrest warrants for people in Florida and several other states on charges of racketeering, illegal gambling and money laundering, among others.

Operating under the guise of a charitable organization for veterans, Allied Veterans of the World leaders were running a $300-million illegal gambling scheme, Ms. Bondi said at a news conference. The company lied about how much of the proceeds from these cafes were donated to charities affiliated with the Department of Veterans Affairs. The company grossed $290 million, an affidavit said, but donated only $6 million.

Ms. Carroll had served as a consultant for the company while she was a Florida House member in 2009 and 2010. Ms. Carroll first became a state lawmaker in 2003, becoming the first African-American Republican member.

In 2010, Ms. Carroll’s association with the company briefly came under scrutiny when she introduced a bill to legalize sweepstakes games. She withdrew the bill, saying it was filed by mistake by an aide, according to The Florida Times-Union. The Legislature is considering banning the 1,000 sweepstakes cafes, which do $1 billion of business a year. They operate under a loophole in Florida gambling laws.

Last year, Ms. Carroll was forced to defend herself after a former aide said in a court filing that she had caught the lieutenant governor in a compromising position with another female aide. Ms. Carroll, who is married and has three children, inflamed the scandal by saying, “Black women who look like me don’t engage in relationships like that.” She later apologized.
