In July, Mr Miller's 97-year-old grandmother, Ruth Glosser, reportedly died due to complications with Covid-19.

The White House denied that coronavirus had caused Mrs Glosser's death, saying in a statement she had "died peacefully in her sleep from old age".

But Mr Miller's uncle produced a death certificate listing "respiratory arrest" and Covid-19 as "a condition leading" to the cause of Mrs Glosser's death.
