My observation is the Democrats are rewriting history to fit their narrative. China did its best to hide the seriousness of the initial outbreak in Wuhan, and initial reports were frequently incorrect and confusing. US social media shutdown links to sites, such as Zerohedge, who showed graphic videos coming from social media in China with people dropping in the streets and reported on speculation from China about a possible lab origin for the virus.
Trump was among the first leader to announce a ban on travelers from China on January 30. Biden denounced the move as hysterical xenophobia, and Democrats continued to push their impeachment trial and viewed the coronavirus as a distraction. The first coronavirus hearing in the House did not occur until February 5. https://docs.house.gov/Committee/Calendar/ByEvent.aspx?EventID=110450
