Former federal prosecutor Lori Lightfoot defeated Toni Preckwinkle in a runoff for Chicago mayor Tuesday. She will be the first openly gay person and first black woman to lead the city.

The Associated Press called the race for Lightfoot shortly before 8 p.m. local time.

With over 91 percent of precincts in, Lightfoot led Preckwinkle 73.7 percent to 26.3 percent, according to the Chicago board of elections website.

Lightfoot pumped her fist in the air and the crowd cheered when she said, “Thank you Chicago!”

“In this election Toni and I were competitors, but our differences are nothing compared to what we can achieve together,” Lightfoot said. “Now that it’s over, I know we will work together for the city that we both love.”

“Today, you did more than make history,” Lightfoot said. “You created a movement for change.”
