Anytime a President makes a stop in Montana, I like to look for people I know in the crowd. It is almost like a live game of "Where's Waldo." I did spot some old classmates and beer drinking buddies in the crowd at the Trump rally last night in Billings. But the internet had their eyes focused on one man, and it wasn't the President.

BuzzFeed has been swarmed with social media posts featuring the mysterious "Plaid Shirt Man." Who is he? His name is still unknown, but he sat directly behind the President's podium in Billings last night. And, was making some peculiar faces during Trump's speech. So much so, that it looks like he was removed from his seat later in the speech.

See some of the best reactions from folks on Twitter.
