The report, which covers the gifts and travel expenses of Supreme Court justices, was released by the court’s ethics office. The report revealed that Justice Alito received a pair of tickets to a concert by the German band Rammstein, a popular rock band known for its heavy metal music. The tickets were gifted to him by a member of the German nobility, who was identified as Baron von der Leyen.

Unlike last year, when Alito reported travel to Rome to attend a religious summit, the conservative justice noted no such trips for 2023. Alito’s report lands at a moment when proposed ethics reforms at the Supreme Court are receiving renewed attention, even though they have gained little traction in Congress. President Joe Biden called for a binding code of ethics for the justices this summer, and Justice Ketanji Brown Jackson became the second member of the court to publicly indicate an openness to the idea. Though the high court adopted its own code of conduct last year, the measure was criticized by ethics experts because it relies on the justices to police themselves.

He has been granted an extension for the past three years. Alito’s annual disclosure reports are typically filled with information about his financial holdings, including stocks, bonds, and real estate. These reports are required by law and are meant to provide transparency about his financial interests.

Alito acknowledged attending a luxury fishing trip on the private jet of a conservative hedge fund manager, Paul Singer, in 2008 – a trip he did not disclose on his annual form. In a Wall Street Journal op-ed last year, Alito downplayed his relationship with Singer and said that a ProPublica story documenting the trip was not “valid.” CNN’s Devan Cole contributed to this report.
