Twitter added fact checking tag to Donald Trump's post about likeliness of fraud in mail ballot voting... It's obvious the envelopes can be stolen from mailboxes and signatures can be forged. It is however questionable how often this happens compared to frauds in other voting methods.

One of the points Donald Trump raised was possibility of illegal immigrants or people with fake identification documents registering as voters and receiving the ballot envelope.

Donald Trump declared he is going to give executive order about social media intervening with authority of the president and freedom of speech.

In the executive order he instructs the administration to prepare changes to legislation so social media companies are legally responsible for content posted on their platform and can be sued. Currently section 230 of Communications Decency Act gives social media companies immunity.
