Members of the Proud Boys are now reportedly turning against former US President Donald Trump and are welcoming President Joe Biden.
The far-right group have previously been loyal supporters of Donald Trump and rose to prominence after he told them to "stand back and stand by" during the 2020 presidential debates.
Since then members of the group have continued to support the controversial former President.
In a private post on the messaging app Telegram in late 2020, the group urged its followers to attend protests against Biden's election victory, claiming voter fraud, the New York Times reported.
"Hail Emperor Trump," the Proud Boys wrote.
Then in early January 2021, some members took part in the Capitol riots where they attempted to stop the counting and certification of the electoral votes.
But the New York Times reported that this week their attitude towards Trump has changed.
They believe the former President's decision to leave office somewhat peacefully to allow for Biden's inauguration on Thursday was "extraordinarily weak".
"Trump will go down as a total failure," the Proud Boys reportedly wrote.
They also saw his denial of responsibility for the Capitol protest as an act of betrayal.
Now members are urged to stop attending rallies and protests held for Trump or the Republican Party.
"When Trump told them that if he left office, America would fall into an abyss, they believed him," Arieh Kovler, a political consultant and researcher who studies the far right told the New York Times.
"Now that he has left office, they believe he has both surrendered and failed to do his patriotic duty."
On Wednesday, the Proud Boys Telegram group decided to welcome Biden as President.
"At least the incoming administration is honest about their intentions," they said.
This comes as more people with ties to the Proud Boys are charged for their part in the Capitol riots.
Around 100 people overall have been arrested so far, but the number is expected to grow as the FBI analyses photos from the riots and identifies rioters, Reuters reported.
