3 Outrageous Things Donald Trump Has Said About President Obama

President Barack Obama's meeting with Donald Trump is going to be awkward.

The pair will come together at the White House on Thursday in their first public step toward a peaceful transition of power in the wake of the real estate magnate's stunning victory on Tuesday. According to his White House schedule, Obama will update Trump "on the transition planning his team has been working on from nearly a year" at 11 a.m. in the Oval Office. Given the terrible things Trump has said about President Obama over the years, things might be a bit uncomfortable.

The self-described billionaire was for years a crusader for the birther movement. Only in September did Trump state publicly that he now accepts Obama was born in Hawaii -- which he was -- at an event largely staged to promote his Washington, D.C. hotel.

Trump has been one of Obama's fiercest critics over the years, expressing his distaste for the president online and in person. A search of Trump's Twitter account for mentions of Obama yields dozens of results, maligning him as "weak," "incompetent," "bad," "failed," "terrible" and "horrible." In a November 2015 tweet, Trump wondered whether Obama was insane. In February 2016, he called him "perhaps the worst president in history." In October 2015, he compared their "60 Minutes" performances.

Great, everyone is saying I did much better on @60Minutes last week than President Obama did tonight. I agree!

In light of Thursday's meeting, here's a look at three of the worst things Trump has said about Obama that might make things a little awkward:

"President Obama has been the most ignorant in our history." -- July 27, 2016

Trump responded to Obama's characterization of a potential Trump presidency as "scary" in an interview with a slam of his own at a press conference with reporters over the summer:

"I think President Obama has been the most ignorant president in our history. His views of the world as he says don't jibe and the world is a mess. He has been a disaster as a president. He will go down as one of the worst presidents in the history of our country. It is a mess."

"Maybe he doesn't want to get it." -- June 13, 2016

In the wake of the shooting at an Orlando nightclub that claimed 49 lives, Trump implied in a handful of interviews that Obama had failed to address terrorism in the United States because he didn't want to.

Trump on the "Today" show:

"Well there are a lot of people that think maybe he doesn't want to get it. A lot of people think maybe he doesn't want to know about it. I happen to think that he just doesn't know what he's doing. But there are many people that think maybe he doesn't want to get it. He doesn't want to see what's really happening."

Trump on "Fox and Friends:"

"He doesn't get it or he gets it better than anybody understands -- it's one or the other, and either one is unacceptable."

And again on "Fox and Friends:"

"I've been right about a lot of things. I don't want congratulations. What I want them to do is be tough and vigilant, our government. Look guys, we're led by a man that either is not tough, not smart or has something else in mind. And the something else in mind -- people can't believe it. People cannot believe that President Obama is acting the way he acts and can't even mention the words radical Islamic terrorism. There's something going on. It's inconceivable. There's something going on."

"Maybe it says he's a Muslim." -- March 2011

Trump long insisted that Obama was not born in the United States, prompting the president to eventually release his long-form birth certificate in April 2011. The real estate magnate also often suggested Obama might be Muslim. He is not, but it would be fine if he were.

Here's an excerpt from a Trump interview with Bill O'Reilly in March 2011 making such a suggestion:

"People have birth certificates. He doesn't have a birth certificate. He may have one but there's something on that, maybe religion, maybe it says he is a Muslim. I don't know. Maybe he doesn't want that. Or he may not have one. But I will tell you this. If he wasn't born in this country, it's one of the great scams of all time."
