Literal Definition of Obstruction.
Therefore, they are Obstructing an official Congressional investigation AND Process of Congress. They need to be ARRESTED and CHARGED with the above.
It’s a INSURRECTION.
The Democrats used some kind of shenanigans so that I am not sure this was an “official Congressional investigation”. In a normal congressional investigation, the minority gets to choose its own members who participate. That certainly did not happen this time with two Trump haters as the only Republicans. Dems in DC are evil but they are smart.
