Financial details were not disclosed. The New York Times reported that people familiar with the bidding said Daschle would receive an advance of more than $500,000.

Barnett would not comment on the finances. He did say the money for the book will be reported in Senate disclosure forms as it is received, and added that Daschle will give the money to charity.

"It's a reflection on these two years," including the Florida recount, the 50-50 split in the Senate, Daschle's role as minority leader, and Sen. James Jeffords' exit from the GOP that made Daschle the majority leader, Barnett said.

It will include Daschle's dealings with the Bush White House, the Sept. 11 terrorist attacks, the war on terrorism, and an anthrax-laced letter addressed to him, which a staff member opened.
