FORT MYERS, Fla. - New revelations show a southwest Florida man who's now a whistleblower against Office Depot is getting money from his former employer's competitors.

David Sherwin tells WINK News its true, but it also doesn't amount to much.

"Basically I ran out of savings and was about to lose my apartment, and some tax watchgroups came to my aid, family members and some competitors of Office Depot in other states," Sherwin said.

Sherwin says he didn't receive any financial help until months after he went public with his accusations against Office Depot in the spring of 2008. He accuses the company of overcharging government clients across the country.

Office Depot has long claimed Sherwin was a disgruntled employee, and in an e-mail to WINK News last month, the company said it believed Sherwin was being paid by their competitors.

Sherwin wouldn't say who's paying him, but says the money amounts to just 15% of his former salary.

"Its basically enough money for me to put gas in my jeep and to live in this apartment and turn the electricity on and put a meal in my stomach," Sherwin said.

Sherwin says the results of his efforts speak for themselves. his allegations have led to investigations in several states, and agencies including Lee County, getting money back.

Sherwin says he gets no money from that.

He says he's even turned down job offers to keep up his crusade on behalf of the public's money.

"I decided I have an obligation to the taxpayers of Florida, Lee County and the United States to stay in this fight," Sherwin said.
