With a record more than 100 million Americans having voted ahead of Election Day due to the Covid-19 pandemic, definitive final results could easily take hours or even days to be tabulated.
The president has also told people around him that he is frustrated with Wray over the FBI director's public statements on issues like voting fraud, Russian election interference and antifa.

Trump, who trails in the polls ahead of the November 3 election, was especially under pressure about the coronavirus that has killed over 217,000 Americans and inflicted deep economic damage.

Other positive cases close to Trump now include his wife Melania, his close aide Hope Hicks, his campaign manager Bill Stepien, two of McEnany's assistants.
