Grassley wouldn’t tweet like a teenager. This has to be a fake or a hack.
Another is that he thinks he's sending out text messages when he's actually tweeting.
It would be very embarrassing if that were true.
The tweets have generated an awful lot of comment - attacks - on twitter.
I suspect somebody hacked his account and the tweets are fake.
If not, somebody get his phone away from him now.
I'm sorry, but it's time to accept reality. This is not a "hack," it's delayed till tomorrow again.
