It shows Donald Trump is simply not trusted when he makes his pronouncements about the Coronavirus pandemic in this country. Trump has tried hard to salvage his reputation by holding daily press briefings on the subject. But he damages himself during those briefings by continuing to tell lies and changing his opinion from day to day.
Only 37% of adults say they have a great deal / good amount of trust in the information Trump is giving. By comparison, 50% say they trust the news media, 72% say they trust state and local government officials, and 84% say they trust public health experts.
