WASHINGTON — President Trump kicked off the new year with more than a dozen Twitter posts castigating his enemies and political foes and complimenting himself.

Seventeen times on his first work day of the new year in Washington, the president thumbed his thumbs at convention. The objects of his attention had a vast and seemingly disconnected range, from taunting Kim Jong-un about his nuclear prowess to flaunting his own successes. But there was more. He made an only-in-the-Trump-era kind of news by announcing a reality-style creation unique in presidential history: awards for the “most dishonest & corrupt media.”

He also threw in a couple of posts that were utterly bland in comparison, good wishes to Senator Orrin G. Hatch, the Republican from Utah who announced his retirement, and a pledge of support for the nation’s veterans. He also showed a fixated consistency by again railing against “crooked” Hillary Clinton and her aide, Huma Abedin.
