NIH Director Jay Bhattacharya is being fact-checked on his off-the cuff responses at a Senate Health, Education, Labor and Pensions Committee hearing in February. The fact-checkers are nine Democratic lawmakers from Massachusetts, only one of whom (Sen. Ed Markey) is on the committee and attended the hearing. In fact, seven of those signing the March 17 letter that questioned Bhattacharya’s veracity aren’t senators. They serve in the House.
