The roundtable, hosted by Sen. Ron Johnson, also focused on COVID-19 vaccine contamination, the development of COVID-19 vaccines as part of bioweapons research and on censorship of journalists and scientists.

Brian Hooker, Ph.D., chief scientific officer for Children's Health Defense (CHD), participated in the roundtable. He told The Defender that the corruption of public health agencies was an "issue [that] came up again and again, with solid data," during the roundtable.

Hooker, who also appeared on Steve Bannon's "War Room" on Monday to discuss how the current childhood vaccination schedule is harmful to children's health, said CHD's presence at the roundtable was important.

"It was very significant for CHD to have a seat at the table at the briefing and also significant how much Sen. Johnson knew of and appreciated our work," he said. "We have a much wider reach than we give ourselves credit for and I believe we'll get more such invitations to speak to and influence congressional representatives."

"Sen. Johnson and several others are highly energized regarding the woeful pandemic response, including the society-wide release of mRNA technology, with an astounding increase in vaccine adverse events," Hooker added.

'Cumulative effect' of childhood vaccine schedule has never been tested

During Monday's roundtable, Hooker provided an overview of the childhood vaccination schedule in the U.S. and its expansion over the years.
