WASHINGTON – The District of Columbia Supreme Court suspended Rudy Giuliani from attorney in Washington on Wednesday pending disciplinary proceedings in New York.

The District of Columbia Appeals Court suspension was automatically triggered by Giuliani’s suspension from practicing law in New York state last month.

Giuliani was an inactive member of the District of Columbia Bar Association when he was suspended on Wednesday.

Giuliani’s admission to the bar in New York was suspended on June 25 in a judgment citing his “false and misleading statements” about former President Donald Trump’s loss of the election.

The suspension in New York is temporary pending the outcome of a full formal disciplinary hearing.

Giuliani is a former New York City Mayor who was once a senior Justice Department official and US attorney in Manhattan.

His mutual suspension in Washington also comes because the same federal agency is under criminal investigation into Giuliani in connection with his work in Ukraine.

Giuliani’s attorney Arthur Aidala did not immediately respond to a request for comment from CNBC on Wednesday.

Since Trump’s defeat in November, the former president and his lawyer have made false claims about the legitimacy of President Joe Biden’s election victory. They claim, without evidence, that Trump was cheated of a victory by widespread electoral fraud in key states.

Giuliani’s false statements about the Arizona, Georgia, and Pennsylvania elections – all states Biden won – were cited in the crushing, 33-page suspension order issued by a five-person appeal panel of the New York State First Judicial Department on June 25th.

This division includes the Bronx and Manhattan, where Giuliani’s law firm is located.
