As White House press secretary Sean Spicer addressed the crowd at a press briefing on Friday, Twitter users noticed something about his outfit was a little off.

His American flag pin was upside down.

This is mildly alarming, because typically an upside down American flag is a sign of great distress. According to Reference.com, people often hang flags upside down as a way to protest issues with the government.

After Spicer carried on about his business for about 10 minutes, John Roberts from FOX News alerted him to the unfortunate mistake.

Spicer was skeptical at first about the fashion advice, but he eventually returned the flag to its upright position.
