Sen. Roger Marshall (R-KS), who has a long history of promoting wild COVID conspiracy theories, told Fox News that President Joe Biden should have to undergo a mental capacity test because Marshall believes there is has been a “deterioration in his mental capacity.”
Marshall has promoted conspiracy theories that falsely suggest that the Centers for Disease Control and Prevention were inflating coronavirus death numbers, which were removed by Facebook, noted the Associated Press in 2020.
Marshall also promoted the off-label use of the malaria drug hydroxychloroquine for COVID in 2020, despite its being unproven as an effective treatment and despite government warnings about using it outside research or hospital settings, reported the Kansas City Star.
