Dear @VP Pence: The virus has incubation period of up to 14 days. Do you get tested every day? If you tested negative 3 days ago it doesn’t mean you couldn’t shed the virus today. Also, these tests are not perfect. I have asked repeatedly & @CDCgov refuses to disclose error rate. https://t.co/aWfgg4utyR— Ted Lieu (@tedlieu) April 28, 2020
