You will never guess so I will just tell you.
It was President Biden's re-election campaign. And they claimed they mostly joined because they thought it would be very funny.
The move is part of the Biden campaign's evolving effort to build an online presence - in preparation for the president's potential rematch with Trump, who is also coordinating an extremely online campaign.
In recent weeks, the Biden White House has begun responding publicly to Trump's diatribes on the platform. After Trump vowed to use the presidency to investigate NBC News parent company Comcast over its "one-side and vicious coverage," Biden's administration responded that such an investigation would "violate the constitutional rights of reporters." It added that the move would be an outrageous attack on our democracy and the rule of law."
Cheers!
Surprise - Surprise - Surprise
