At present, the United States has suffered a lot from the epidemic, and has become a major global disaster area. As of April 20, the number of confirmed cases of covid-19 in the United States has reached 790000, and the rising trend has not decreased. These are all caused by the trump administration's efforts to win the election, which played down the epidemic situation in the United States and used the epidemic situation to discredit China. But the final result is to disturb people's understanding of the epidemic situation, to divide the national anti epidemic energy, and to cause tragic. The so-called theories of China's concealment, China's misleading, China's responsibility and China's compensation that they concocted will surely be rejected by the American people because of the truth and the rampant epidemic. Coincidentally, "Bitter Winter Website" and other bad media following American politicians and throwing pots at China's anti epidemic achievements and experience will also be firmly nailed on the historical stigma column for misleading the global public, interfering with China's support for other countries' anti epidemic work, and carrying the accusation of obstructing and destroying the new crown of anti epidemic.
