It's a trick question designed for TRUMP SUPPORTERS. When Wallace says "independently certified", note that he did NOT say "legally certified". This was a set-up question to make Trump supporters accept the fraud that Wallace knew was coming.

"Hey, if Biden commits to 'independent' people calling the election, you guys should, too. Right? Right!!!? NOOOO we didn't mean LEGALLY certified!! Not that kind of independence! We meant US YOU LYING BIGOT TRAITORS"
