No. This case was launched by Trump's DOJ in 2020 [0], in conjunction with the Republican Attorneys General representing a bunch of states that Trump won handily this election. Trump's Attorney General Barr released a statement when they announced the lawsuit [1]:
> Today, millions of Americans rely on the Internet and online platforms for their daily lives. For years, there have been broad, bipartisan concerns about business practices leading to massive concentrations of economic power in our digital economy. Hearing those concerns, I have made it a primary commitment of my tenure as Attorney General for the Department of Justice to examine whether technology markets have been deprived of free, fair, and open competition.
This case has never has been a partisan issue. It was opened by a Republican DOJ and pushed through by a Democratic DOJ, and there's no reason to believe that the Republicans won't see through what they started.
