Hillary Clinton is getting attention after changing her Twitter profile this week with a shot of her wearing a face mask that reads simply: “VOTE.”

“This time more than any other time, we have to turn out,” she said in a recent interview with Lisa Ling, according to People. “Get everybody you can registered to vote. There are lots of ways to reach out. This is going to be labor-intensive, but there’s no other way to do it.”

According to a Clinton aide, the image had a real purpose.

“Trump gave people very bad advice about this early on, so we’re all paying catch up,” the aide contends with People. “So putting the mask on — no makeup — was about signaling how important this is for everyone to do.”

Of course, Trump has refused to wear a face mask when visiting facilities throughout the month, which goes against the Centers for Disease Control and Prevention’s guidelines.

You go, Hill!
