Hawley told "Hannity" that the U.S. government had offered to send medical teams and scientists to China in order to aid their recovery and find out exactly what happened in the country.
"China said no ... they have been lying about it and sitting on it for weeks and weeks and weeks and that has cost the world thousands of deaths, it's cost us here in this country," Hawley said.
The senator also called for an international investigation that will "hold the Chinese government to account" and fight Beijing's state-run "propaganda machine" that he said has helped spread rumors implicating the American military in the pandemic.
"We need to make it clear -- and we need an international investigation to make it clear for the world -- that this started in Wuhan, China, that the Chinese government lied about it, they jailed the doctors who tried to blow the whistle on it, they cost the world thousands of lives and billions of dollars. And here’s the other thing, they ought to be on the hook to pay back some of it."
Hawley also said America will eventually recover and return to the global community stronger than before -- but reiterated that China must be held responsible.
He also slammed House Speaker Nancy Pelosi, D-Calif., for inserting pages and pages of pork barrel spending into her caucus' version of the coronavirus aid bill.

"We have our economy at a point of crisis and we are in a public health crisis, we've got people who are losing their jobs, we've got people desperate for medical care. And ... she's trying to put in abortion funding into this bill, she's trying to get funding for sanctuary cities, she's trying to get amnesty," Hawley fumed. "You've got to be kidding me -- I’m not voting for any of that stuff. Let’s get this thing done."
