President Trump had a big day today, kicking it off with breakfast with the king of Finland, followed by the summit with Russian President Vladimir Putin.

But the biggest part of President Trump's day? Calling into The Michael Rock Show to comment on Niall Horan.

Trump was a little fiery because he says he couldn't understand the Irish-born singer during his interview with Fun 107 this morning.

He was, however, ready for Amazon Prime Day.

Interestingly enough, Amazon had major issues of its own today, it's biggest shopping day of the year, because the site apparently couldn't keep up with the volume of sales.

As President Trump might say, "Sad."
