Former New Jersey Governor Chris Christie, a prominent ally of Donald Trump has urged him to drop his efforts to overturn his loss to Joe Biden in the US presidential election.
The former governor called the president’s legal team a “national embarrassment”.
President Trump has refused to concede the election, making unsubstantiated claims of widespread electoral fraud.
Many Republicans have supported his legal efforts but a small but growing number have broken ranks.
Speaking to ABC’s This Week programme on Sunday, Mr Christie, a former New Jersey governor, said: “Quite frankly, the conduct of the president’s legal team has been a national embarrassment”.
He said the Trump camp was often discussing election fraud “outside the courtroom, but when they go inside the courtroom they don’t plead fraud and they don’t argue fraud”.
“I have been a supporter of the president’s. I voted for him twice. But elections have consequences, and we cannot continue to act as if something happened here that didn’t happen.”
Mr Christie was the first governor to endorse Mr Trump as a presidential candidate back in 2016. He also helped prepare the US president for his debates with Mr Biden earlier this year.
