SUNDAY TIMES WEB DESK:Not so for US President Donald Trump, who kicked off 2019 in a characteristically belligerent fashion, tweeting an all-caps message to his critics, telling them to “CALM DOWN AND ENJOY THE RIDE.”

“HAPPY NEW YEAR TO EVERYONE, INCLUDING THE HATERS AND THE FAKE NEWS MEDIA! 2019 WILL BE A FANTASTIC YEAR FOR THOSE NOT SUFFERING FROM TRUMP DERANGEMENT SYNDROME,” he wrote.

“JUST CALM DOWN AND ENJOY THE RIDE, GREAT THINGS ARE HAPPENING FOR OUR COUNTRY!”

The tweet was followed a short while later with a more conventional — and decidedly more subdued — greeting: “Happy New Year!”

The president, known for his round-the-clock use of the social network, later returned to some familiar recent themes, attacking opposition Democrats for not supporting his proposed wall along the southern border with Mexico and accusing them of not caring about “all of the crime and drugs that Open Borders bring.”
