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.
