Federal Election Commission commissioner Ellen Weintraub posted an extensive fact-checking thread to Twitter late Wednesday debunking claims by President Trump and some Republicans that mail-in voting can lead to fraud.

Why it matters: Weintraub weighed in after Trump threatened to take action against Twitter for fact-checking him on his earlier unsubstantiated posts claiming mail-in ballots in November's election would be fraudulent, and she directly addressed Twitter's action against the president in her post.
