What will happen to Dr Fauci's pardon after Trump calls Biden's last-minute clemency orders void?

Though Trump only mentioned those who were in the January 6 committee which would include Bennie Thompson and Liz Cheney, Biden also pardoned his son Hunter Biden and Dr Fauci. If Dr Fauci's pardon is also withdrawn, he may face an investigation into his role during the pandemic. When Biden pardoned Fauci, Fauci accepted it and said he did no crime.
