A timeline of key events in the Jack Abramoff investigation:
— Abramoff and associate Adam Kidan purchase the SunCruz Casinos fleet of gambling boats.
— Abramoff donates more than $100,000 to President Bush's re-election campaign.
— Sept. 29: Abramoff refuses to answer questions from the Senate Indian Affairs Committee about his lobbying work on behalf of American Indian tribes and casino issues. The Senate committee's staff concluded after a seven-month investigation that Abramoff and partner Michael Scanlon, a former aide to Rep. Tom DeLay, R-Texas, had charged six tribes in six states at least $66 million for the lobbying and may have manipulated at least two tribal elections to ensure they would get contracts with tribes.
— Aug. 11: Abramoff and Kidan indicted by a Miami federal grand jury on fraud charges in the 2000 casino boat deal. Federal prosecutors say the pair faked a $23 million wire transfer to make it appear that they were making a significant contribution of their own money into the deal. Based on that transfer, lenders Foothill Capital Corp. and Citadel Equity Fund Ltd. agreed to provide $60 million in financing for the purchase.
