Here’s what progs are saying about govt Twitter cooperation.in 2020 Trump was POTUS not Biden. Is working in cahoots with DNC working with govt? It can be argued that it is not. The DNC is not a govt organization. It is defensible to see these joint operations and say they were not speech limitation by govt and therefore not a 1st Amendment violation. Of course the FBI participation raises other issues.
Kamala Harris was a US Senator at the time.
