Justice Clarence Thomas delayed releasing his annual financial disclosure form with the justices on Wednesday after recent revelations cast scrutiny on his travel, gifts and real estate dealings with a conservative billionaire donor from Texas.

Like Justice Thomas, Justice Samuel A. Alito Jr. also asked for a 90-day extension to file the forms, which detail gifts, investments and other financial holdings, according to the Administrative Office of the U.S. Courts, which handles the financial forms and the database where they are publicly disclosed.

The financial disclosures, particularly that of Justice Thomas, have drawn heightened interest after reports that Harlan Crow, a Texas billionaire and longtime Republican donor, had hosted Justice Thomas on luxury vacations aboard his superyacht, flown him on his private jet and paid private school tuition for the justice’s nephew. Mr. Crow also bought the justice’s childhood home, where his mother still lives, according to ProPublica. Justice Thomas did not include those dealings on his financial disclosures.
