Rudy Giuliani goes before an ethics panel in Washington, D.C., next week over his promotion of unfounded voter fraud arguments in Pennsylvania federal court, a case that one ethics expert says could have repercussions for other lawyers in former President Donald Trump’s orbit.

The hearing before a hearing committee of the D.C. Bar’s Board of Professional Responsibility kicks off Dec. 5, and is expected to last at least a week. The committee will issue a non-final report and recommendation to the board.
