I don't think you understand what Kamala just did.
Kamala Harris is the current Vice President of the United States.
The Vice President saying Trump is Hitler on the podium in front of the seal is essentially saying the Executive Branch of the United States of America supports and encourages violence against Trump and his supporters.
She just declared war on Trump and us.
Now you see why the Dod signed the directive declaring the military can kill US citizens on US soil two weeks ago.
