What Do You Think of Joe Biden testing positive, then negative, then positive for COVID-19?

Last week, President Biden tested positive for COVID-19 and self-isolated, then he tested negative (twice), and now he's tested positive again, resulting in another self-isolation and his planned international trip canceled.

What do you think of that? Were the negative tests false negatives? Has he been exposed to the SARS-2 virus again? Or maybe the latest test is a false positive?
