President Trump tweeted about alleged problems with the New York election system, without providing any supporting information, after the last election was held in the state more than one month ago with no races outstanding.
New York Mail-In voting is in a disastrous state of condition. Votes from many weeks ago are missing – a total mess. They have no idea what is going on. Rigged Election. I told you so. Same thing would happen, but on massive scale, with USA. Fake News refuses to report!

Trump has repeatedly tried to undermine mail-in voting, seeing it as a disadvantage to himself and republicans. There is no evidence–from Trump or any other source–that any election was rigged.
