See I am old and skeptical. CEOs don't just let the President announce and get credit for job creation if they don't get something for it. It's Sprint that's creating the jobs, not Trump. By letting him claim credit for it they are doing him a favor. They are going to call on the favor at some point or another. I firmly believe it's about the merger.
Take the $256M battery plant in Buffalo Between Tesla and Panasonic. Don't you think that was a quid pro quo from Trump? As in don't touch the federal subsidies for renewables?
If I was running either of these companies I would definitely make a deal where I got something out of it. Wouldn't you?
