An appeals court on Thursday suspended Rudy Giuliani from practising law in New York because he made false statements while trying to get courts to overturn Donald Trump’s loss in the 2020 presidential race.
An lawyers' disciplinary committee said in its motion to suspend Mr Giuliani’s licence that there was “uncontroverted evidence” he made false statements to the courts, the public and politicians as he pushed theories that the election was stolen through fraud.
“This country is being torn apart by continued attacks on the legitimacy of the 2020 election and of our current President, Joseph R Biden,” the committee wrote.
“The hallmark of our democracy is predicated on free and fair elections.
"False statements intended to foment a loss of confidence in our elections and resulting loss of confidence in government generally damage the proper functioning of a free society.”
The ruling will prevent Mr Giuliani from representing clients as a lawyer.
A message seeking comment about the ruling was sent on Thursday to Mr Giuliani and his lawyer.
He was the main mouthpiece for Mr Trump after the 2020 election.
Standing at a press conference in front of Four Seasons Total Landscaping outside Philadelphia on the day Mr Biden was declared the winner, Mr Giuliani said they would challenge what he claimed was a vast conspiracy by Democrats.
Misleading information about the 2020 election helped to encourage an angry mob of pro-Trump rioters to storm the US Capitol on January 6, in a shocking effort to stop the certification of Mr Biden’s victory.
Since then, Republicans have pushed for stricter voting laws nationally.
