A federal judge overseeing a lawsuit filed by Amazon, and who recently disclosed his wife held stock in the company, said claims he should recuse due to a conflict of interest are “almost insane” and “100% flawed.”

U.S. District Judge Liam O’Grady disclosed earlier this month that, following a Wall Street Journal investigation, he learned his wife held $22,000 of stock in Amazon in a brokerage account while he was assigned to a suit Amazon brought against a Colorado real estate developer and a former Amazon employee alleging a kickback scheme. The defendants, WDC Holdings, are requesting a new judge be assigned.
