A top Supreme Court lawyer who co-founded a popular blog about the high court was indicted Thursday in Maryland on federal tax evasion charges that allege he failed to declare millions of dollars in poker winnings and used his law firm’s money to pay his gambling debts.

SCOTUSblog publisher Tom Goldstein, who is also charged with making false statements to two mortgage lenders, has appeared before the Supreme Court more times than nearly any other attorney in private practice in modern times.

The indictment alleges that for the tax years 2016 through 2021, Goldstein willfully failed to pay more than $5.3 million in taxes he owed the IRS.
