A prominent attorney, who is known for his work at the Supreme Court, has been accused of tax evasion related to his poker winnings.

• A prominent Supreme Court attorney was charged with federal tax evasion in Maryland due to his alleged failure to report millions of dollars in poker winnings and using firm funds to settle debts.
• Nearly no other attorney in private practice has appeared before the Supreme Court as many times as Tom Goldstein, who is also facing charges of making false statements to two mortgage lenders.
• Goldstein has taught at Harvard Law School and represented both Al Gore and Google in significant legal cases.

A lawyer who founded a well-known blog about the Supreme Court was charged with federal tax evasion in Maryland on Thursday. The charges claim that he did not declare millions of dollars in poker winnings and used his law firm's funds to settle his gambling debts.

Nearly no other attorney in private practice has appeared before the Supreme Court as many times as Tom Goldstein, who is also facing charges of making false statements to two mortgage lenders.

Goldstein, 54, has taught at Harvard Law School and represented then-Vice President Al Gore in the Bush v. Gore case at the Supreme Court, which ended the recounting of Florida ballots in the disputed 2000 presidential election. He also successfully represented a client in a Supreme Court case where the use of software code in Android was accused of violating U.S. copyright law.

In November, Goldstein penned a New York Times guest essay advocating for the cessation of criminal proceedings against President-elect Trump.

Goldstein has been described as an "ultrahigh-stakes power player" who frequently played in matches or series of matches with stakes totaling millions, and even tens of millions, of dollars, according to the 22-count indictment against him in U.S. District Court in Maryland.

He used legal fees intended for his Bethesda, Maryland, law firm, Goldstein & Russell, to settle his poker-related debts.

The indictment claims that from 2016 to 2022, Goldstein engaged in or pursued intimate relationships with over a dozen women, and covered their travel and other expenses, despite owing "significant amounts of money to the Internal Revenue Service."

According to the indictment, four women were allegedly hired by his firm and paid with health benefits despite performing "little or no work for the firm."

Goldstein, who founded SCOTUSblog with his wife in 2002, announced his retirement from his legal practice and firm, which was later renamed.

In 2016, Goldstein used over $1.1 million of company funds to settle personal debts, including gambling debts owed to poker players.

In addition to the understatement of his gambling winnings by more than $3.9 million on his 2016 federal tax return, he also allegedly failed to report more than $3.4 million in gambling income on his tax return for 2017.

In 2021, Goldstein allegedly submitted false mortgage applications to two separate mortgage lending companies, seeking financing to purchase a $2.6 million home in Washington, D.C., according to the U.S. Attorney's Office in Maryland.

"Goldstein allegedly concealed millions of dollars of liabilities on his mortgage applications, including over $14 million he owed on two promissory notes and taxes he owed to the IRS. As a result, he obtained a $1.98 million loan from one of the mortgage lenders."

CNBC has reached out to Goldstein for comment.
