Dr. Anthony Fauci was noticeably absent from the White House daily coronavirus briefing for the second day running on Monday. 

The coronavirus expert admitted in an interview over the weekend that he has to tell Donald Trump facts four times to get his point across.

Since the chat with Science was published Sunday he has not been seen at the press conferences led by the president. 

His absence caused concern for many Americans online, with Twitter users rushing to question where the virus expert had disappeared to. 

One wrote: 'Where the holy hell is the one person we all trust? Where is Dr. Fauci?'  

Another added: 'Where is Dr. Fauci. I want facts! I don't like when there is no fauci!' 

Even NBC anchor Maria Shriver seemed concerned, tweeting: 'I'm missing Dr. Fauci. Not there yesterday, not there today. He was the one that made me feel reassured, he was the one that made me feel safe. Where is he? I need him!'
