Again, the outright lies he tweeted were not something that were provably false in less than 24 hours.
Just consider his infamous "Funding secured" tweet. I considered that a lie, but there is obviously enough wiggle room/deniability over what "secured" actually means. That's not the case here.
In any case, the deadline has already passed. If there were to have been mass layoffs before the Nov 1 deadline, it's too late.
