George W Bush's brother Neil outlined business deals and admitted to sexual liaisons with strangers in his divorce proceedings, a news agency has said.
The president's brother was divorced earlier this year
Neil Bush was to receive $2m in stock options from a semiconductor firm despite having no education in the field, he told the court in March.
He also said he had sex with women in Asia who had come to his hotel room. He said they had not asked to be paid.
"It was very unusual," Mr Bush said in response to a lawyer's question.
He told the court he did not know if they were prostitutes, the Reuters news agency reported, saying it had seen a transcript of the 4 March deposition.
Neil Bush is now divorced from Sharon, his wife of 23 years.
He is the third child of former President George Bush and his wife Barbara.
He came under heavy criticism when a bank of which he was director collapsed in the 1980s - and was bailed out by the government at a cost of $1bn.
He denied wrongdoing in the failure of Silverado Savings & Loan, but was fined $50,000 and banned from banking.
In the divorce proceedings, Sharon Bush's lawyer pressed him on why a semiconductor firm would offer him $2m in stock.
Mr Bush signed a contract with Grace Semiconductor Manufacturing Corp in August 2002.
The firm is backed by the son of former Chinese President Jiang Zemin.
Marshall Davis Brown, the lawyer, suggested Mr Bush had "not a lot of demonstrable business experience that would bring about a company investing $2m in you".
"I personally would object to the assumption that they're investing $2m in me," Mr Bush replied.
He said has was acting as a consultant for the company and sitting on its board of directors.
He added that he had not yet received stock from Grace.
Reuters said that Grace, Mr Bush and Mr Bush's divorce lawyer declined to comment or were unavailable.
