President Trump recently took a visit to the U.S. Open. While he was there, he was caught on camera putting something in his mouth — specifically, a small blue tablet.

This immediately sent the internet into a spiral. What could it be?!

According to The Daily Beast, we only know of Trump taking a few medications for certain: rosuvastatin, ezetimibe and finasteride. Of those, only finasteride is commonly sold in a blue color, so it could be that.

However, given that it’s the internet, there are plenty of other theories. Some say that the pill is Hygroton, which is generally used for edema and can come in a blue color. Others take a more innocent approach, saying that the President was simply chomping down on a mint.

What’s the truth? Who knows, but I gotta say, no matter what it is, it’s a little weird to hold it in your teeth like that.
