WASHINTON, D.C.(WNAX)- There are still questions and suspicions about the origin and spread of the coronavirus last year in China.

South Dakota Senator John Thune says China has not cooperated in finding the source of the pandemic.

Thune says it may be difficult to hold China accountable.

Thune says China’s military has become more aggressive in parts of Asia.

Thune says Members of Congress continue to push the Biden Administration to put pressure on China to get more information on the spread of the virus.
