Appearances can mean a lot in politics. One top Democratic presidential candidate drew some attention Friday, not for his comments but rather for a visible injury.

Sen. Bernie Sanders of Vermont sat on a health-care roundtable in Charleston, South Carolina, with a large bandage above his left eye, drawing curiosity as to what caused it. Sanders did not acknowledge the bandage or any type of injury during the panel but was open when reporters made inquiries.

He said he accidentally cut his head "on the edge of a glass shower door" earlier in the day. Sanders sought out a local walk-in clinic and received seven stitches for the cut and also received a clean bill of health.

Sanders' spokeswoman Arianna Jones reportedly said that Sanders went to the walk-in clinic "out of precaution" and had not injured himself by slipping. Jones also confirmed he was on track for all of his scheduled events.

The injury came at a time when Sanders spent two days discussing health care.

Sanders on Thursday spoke to 1,600 people inside a gym at Royal Missionary Baptist church, where he criticized the private health care industry and championed single-payer Medicare-For-All health care.

"Tonight, we say very clearly to the private health insurance companies, whether you like or not, the United States of America will join every other major country on Earth and guarantee health care to all people as a right," Sanders told the crowd.

He dismissed critics of his health care plan and referenced the U.K., Germany and France for implementing similar systems.

"If they can guarantee health care to all people as a right, don't tell me the United States of America cannot as well," Sanders said.

Sanders echoed these sentiments on Friday with the bandage on his forehead.

"We have a system in which insurance companies and drug companies make billions and yet you've got tens and tens of millions of Americans who cannot afford to go to the doctor," Sanders said. "To me, that is pretty crazy stuff."
