Although not always correct, according to Ballotpedia there are only 2 candidates for American Samoa Delegate to congress, incumnbent Eni F.H. Faleomavaega, Democrat and challenger Aumua Amata, Republican.
I searched Faleomavaega and the only reference to his illness is from a conspiracy website.
He does not look good in some of his pictures on Facebook, but certainly not on deaths door.
The local American Samoa news websites are severely lacking in info on any local politics let alone the congressional race.
please see post 10.
