Three Democrats tested positive were allowed to vote for Pelosi. So why blame the Republicans? Yes my friends three Democrats who had tested positive were allowed in the House to vote for Pelosi. So why are the Republicans being blamed for infecting the other Democrats?

Also the Democrats who just tested positive were wearing masks. So why did they get the virus? Remember we were told that the mask was the best defense against the virus. Were we lied to? Or maybe the three who tested positive were not social distancing. Finally why haven't the Republicans tested positive? The maskless ones.
