made through the investment bank he used to head, Alex. Brown. The 9/11 Commission Report stated: A single U.S.-based institutional investor with no conceivable ties to al Qaeda purchased 95 percent of the UAL puts on September 6 (2001) as part of a strategy that also included buying 115,000 shares of American on September 10. Similarly, much of the seemingly suspicious trading on September 10 was traced to a specific U.S.-based options trading newsletter…which recommended these trades. Blackwater At a November 14, 2007 House oversight committee hearing about Blackwater, investigating allegations of improper interference by Krongard's brother, Howard, in Justice Department investigations of Blackwater and other State Department contractors, Chairman Henry Waxman stated that A. B. Krongard was on "Blackwater's advisory board". Howard Krongard at first denied that his brother had any connection with Blackwater, saying: I can tell you, very frankly, I am not aware of any financial interest or position he has with respect to Blackwater. When these ugly rumors started recently, I specifically asked him. I do not believe it is true that he is a member of the advisory board that you stated. And that's something I think I need to say. However, when confronted with a July 26 letter from Blackwater founder and CEO Erik Prince to Buzzy Krongard asking him to join Blackwater's advisory board, followed by a September 5 letter welcoming Krongard to the board and a report from Rep. Elijah Cummings stating that Buzz Krongard had been expected to attend a Blackwater board meeting earlier that week, Krongard said he had called his brother during the ensuing break in the hearings and learned of this conflict of interest for the first time, saying "I'm not my brother's keeper, and we don't discuss our business with each other". He then recused himself from the investigation. Committee chairman Henry Waxman issued a memorandum summarizing the discrepancies between the two brothers' recollections of what Buzzy told Howard.
