Tulsa rally attendance lower than expected; Trump mocks protestors, Coronavirus and Biden

Trump's first re-election campaign rally since March had lower attendance than expected. At least one-third of the BOK center in Tulsa remained empty and the outdoor venue saw so little people that Trump and Pence cancelled their appearance there.
At the rally, Trump touched on several topics. He falsely claimed protestors outside the BOK center were violent, saying "we had a bunch of maniacs come and sort of attack our city", but coverage showed hardly any interaction with Trump supporters and protestors.
Trump went on to describe Biden as a "helpless puppet of the radical left" and a "puppet for China". He further stated that he plans to "slow down testing" for Covid-19, which he referred to as "kung flu" and "China virus".
