According to TMZ.com, Fischer took the records after a dispute with clinic owner Anthony Bosch.
“Of course my client is going to talk with MLB,” Fischer’s attorney, Raymond Rafool, told the Daily News. “My client wants to do the right thing.”
According to TMZ, which first reported the meeting, Fischer will be paid a "consultant fee” for his testimony, which TMZ reports will impact 100 players.
Rafool, however, denied that there would be any payment involved.
“My client has not agreed to any consulting fee — I don't know where (TMZ) is getting that information,” he told the Daily News. “That has not been discussed yet.”
Last month, the Miami New Times reported that Fischer had sought out MLB officials, who addressed his claim that he was offered money by the league.
"Mr. Fischer approached us, and it was clear from the beginning he was seeking compensation for documents or verification," Pat Courtney, a spokesman for MLB, told the paper. "We had discussion with him on a number of occasions but never reached any agreement."
