WEST PALM BEACH, Fla.—Former U.S. Rep. Mark Foley, who resigned from Congress amid an Internet teen sex scandal, has racked up nearly a half-million dollars in legal fees paid from his campaign account, according to recent filings.

Foley spent $277,367 on legal fees from February to April, according to filings with the Federal Election Commission. That’s on top of the $206,000 in campaign cash Foley spent on attorneys from last November to January.

Foley’s filing indicated that he still has about $1.4 million in campaign cash as of July 15.

The FEC has ruled that such expenditures for legal fees that arise from congressional duties are generally lawful, but Foley must still return money to donors who request refunds.

Foley’s legal fees were paid to the Washington, D.C. law firm of Zuckerman Spaeder LLP. A spokeswoman for the firm declined comment last week.

In a May letter to the FEC, Foley wrote that his legal fees are being spent “in responding to an investigation that was initiated by then-Speaker of the House Dennis Hastert.”

State and federal authorities continue to investigate whether Foley broke any laws.

“It is still active, but I think we’re coming to a close in hopefully the weeks to come,” said Kristen Perezluha, a spokeswoman for the Florida Department of Law Enforcement.

Foley resigned from Congress in September after being confronted with sexually explicit Internet communications to male pages who had worked on Capitol Hill.
