Talk show host Oprah Winfrey was among those who took part in early voting in Chicago. On her show on Friday, Winfrey revealed she had problems inside the polling booth.

Oprah Winfrey: “When I voted yesterday electronically, the first vote that you vote for on the ballot is the presidential candidate. And so, I hadn’t — you know, it was my first time doing electronic, so I didn’t obviously mark the X strong enough, or I held down too long, because then when I went back to check it, it had not recorded my presidential vote. And I was like, ohhOhhOh. And so the woman is walking around. And she says, why are you going back, why are you going back? I go, because it…didn’t…record…my presidential vote! So I went back and double-checked. So that’s why they have the, you know — check. Make sure you double check.”
