Now granted Hunter has not been convicted of any crime and is innocent till proven guilty but we also had to listen to people ask will Trump pardon himself will he pardon his children for four years so it seems fair to ask this about the Biden’s [sic].
Rump cannot pardon himself, or anybody else, without specifying what is being pardoned. Since "Hunter" doesn't have a judgment against him either, that's also impossible.
You however, cannot be pardoned for using an apostrophe to form a plural in English. The plural of Biden is
Bidens, not "Biden is".
