She teamed up with actress Sarah Jessica Parker, a fellow Obama supporter, to host a dinner in New York City along with the president and first lady.
"I'm so lucky in my work that I'm able to meet some of the most incredible women in the world — women like Sarah Jessica Parker and Michelle Obama. These two wonderful women and I, along with the president, are hosting a dinner in New York City to benefit the Obama campaign," Wintour says in a Web video released by the campaign.
The Obama team has hosted similar campaign events, where supporters can enter to dine with the president and first lady.
The recurring "Dinner With Barack" contest gives winners an intimate audience with the Obamas. In May, two women were flown to Los Angeles to join the president at a fundraiser hosted by George Clooney.
"It will be a fantastic evening and you can join us. We're saving the two best seats in the house for you … Sarah Jessica and I both have our own reasons for supporting President Obama and we want to hear yours, so please join us," Wintour continues.
Playing off of her reputation as a demanding and intimidating boss — the book and movie "The Devil Wears Prada" were supposedly inspired by the Vogue chief — Wintour reminds entrants, "just don't be late."
