(WND) U.S. Sen. Ron Johnson, R-Wis., led a roundtable discussion on Wednesday with leading health scientists and experts titled “COVID-19 Vaccines: What They Are, How They Work, and Possible Causes of Injuries.”

Hearing starts at 8 minute mark 

Among the scientists were Drs. Peter McCullough, Robert Malone, Harvey Risch, Ryan Cole, Pierre Cory, Paul Alexander and Paul Marik. Others, such as former Wall Street analyst Edward Dowd, have conducted statistical investigations of the impact of the vaccines.

And a number of people testified of severe, life-changing injuries they are suffering that they believe were caused by the COVID vaccine.

Johnson also asked officials such as Biden COVID adviser Dr. Anthony Fauci, CDC Director Rochelle Walensky and Pfizer CEO Albert Bourla to testify. To no one’s surprise, none accepted the invitation.
