Tom Perez, the Democratic National Committee chairman who will decide which city gets his party's 2020 national convention, said Sunday that Milwaukee, Houston and Miami are "all in the hunt."

The three finalist cities have waged monthslong campaigns to secure the convention, where Democrats will nominate their presidential nominee.

A decision was expected this week, but that could be pushed back, Perez indicated.

Appearing on "Fox News Sunday," Perez was asked point blank by moderator Chris Wallace: "Will Milwaukee host the 2020 Democratic Convention?"

"We have three finalists, Milwaukee, Houston and Miami," Perez said. "They're all in the hunt."

"We're hoping to make the decision within the next few weeks, at the most," Perez added. "My goal is to make it by the end of the month. I hope to keep that. But my goal is to get it right and if it takes a few days over then we're going to make sure we get it right. We have an embarrassment of riches, quite frankly."
