Updated as of 5:29 p.m. | The United States might not have such a civil transition of power after all.

Donald Trump, set to be sworn in on Jan. 20, used his preferred form of communication — Twitter — to slam outgoing President Barack Obama on Wednesday for what he sees as overly critical statements.

Trump wrote that he is “doing my best to disregard the many inflammatory President O statements and roadblocks.” The businessman and former reality show host then proclaimed an end to what had been a transition process with few public jabs with Obama. But later in the day, he seemed to contradict himself.

Obama, before it was known which party won the White House, set in motion orderly changes necessary for a new administration, a top priority for his staff during his final year. While there were some public disagreements on policy matters, as well as differing assessments on whether Russia meddled in the election, Obama used part of his year-end press conference earlier this month to promise a drama-free transition.
