What did Donald Trump do today?

He had a bit of trouble making up his mind about his feelings toward President Obama.

At 6:07 a.m., Trump tweeted his anger at Obama and his "inflammatory... statements and roadblocks," saying that he was "doing [his] best to disregard them." It's not clear what specific "roadblocks" Trump had in mind, but he has been visibly upset for several days now over Obama's statement that he could have beaten Trump if he could have run in 2016.

Within hours, however, Trump was telling reporters that the transition was going "very, very smoothly," later adding, "I'm getting along very well with [President Obama] other than a couple of statements that I responded to and we talked about it and smiled about it and nobody is ever going to know because we are never going to be going against each other."

Trump was in Florida today and spoke briefly with Obama between his tweet and his press comments. It's not known if Obama made any direct effort to pacify Trump, or whether Trump's mood regarding the state of the transition improved on its own.

So what does this matter?

• It's not a good sign if both sides of a president's mood swings are visible to the public.
