President Barack Obama has repeatedly pledged a smooth transition

President-elect Donald Trump tweeted that was 'NOT!' the case

CNN  — 

Donald Trump accused President Barack Obama on Wednesday of making “many inflammatory statements and roadblocks” during the President-elect’s transition to the White House.

“Doing my best to disregard the many inflammatory President O statements and roadblocks. Thought it was going to be a smooth transition - NOT!” Trump tweeted.

Trump appeared to reverse himself later Wednesday when, responding to a reporter’s question in Florida, he said the transition was going “very, very smoothly.” The President-elect also said he spoke with Obama Wednesday in what he termed a “nice conversation,” and later in the day, he said he was getting along well with Obama, “aside from a few statements.”

Trump’s morning tirade comes after Obama said in an interview published this week that he could have beaten Trump in the 2016 election if he were eligible to run a third time.

“I am confident in this vision because I’m confident that if I had run again and articulated it, I think I could’ve mobilized a majority of the American people to rally behind it,” Obama told his former senior adviser David Axelrod in an interview for the “The Axe Files” podcast, produced by the University of Chicago Institute of Politics and CNN.

Obama’s exit interview: I could’ve won again

Although Hillary Clinton beat Trump in the popular vote by almost 2.9 million ballots, the business mogul won more electoral votes and thus the presidency.

Trump disputed Obama’s claim that he could have won, citing voters’ displeasure with the Affordable Care Act, terrorism and the economy.

“President Obama said that he thinks he would have won against me. He should say that but I say NO WAY! - jobs leaving, ISIS, OCare, etc.,” Trump tweeted Monday.

Speaking to reporters on Wednesday, Trump said it will never be known who would win in a hypothetical matchup between him and Obama.

“We’re never going to be going against each other in that way,” he said.

For the most part, Trump and Obama have steered away of directly criticizing one another since the election. The two met in the White House two days after Trump was elected and have talked by phone several times since then.

“I must tell you, you know, I never met him before this. I never spoke to him before this. I really – I do like him,” Trump previously said. “I love getting his ideas. And I may differ in many cases. I differ very greatly.”

Wednesday’s call “focused on continuing a smooth and effective transition,” White House spokesman Eric Schultz said, adding that the two men have “committed to staying in touch over the next several weeks.”
