Pelosi is guilty of sedition and fomenting insurrection as she advised illegals slated for deportion to hide, not answer door knocks, etc.
No. She's guilty of obstructing justice, not the other things you mentioned.
To be guilty of fomenting insurrection, she would have to urge armed resistance to military or law enforcement personnel.
To be guilt of sedition, she would have to urge violent overthrow of the government.
Sedition and insurrection would be true IF the actions were attributable to US citizens.
