From CNBC here:
President-elect Donald Trump touted resilient holiday spending and a strong stock market in a self-congratulatory tweet on Monday evening.
“The world was gloomy before I won – there was no hope. Now the market is up nearly 10% and Christmas spending is over a trillion dollars!” the president-elect tweeted on Boxing Day.
It’s pretty clear that Trump sticks with Twitter because it’s impossible to tell whether he’s talking out his ass or his face if he’s just blasting tweets.
