Chicago Mayor Rahm Emanuel (D) is headed to Iowa.

The former White House chief of staff will keynote the Democratic Partys Jefferson-Jackson dinner Nov. 19 in Des Moines. It is one of the state partys biggest fundraising events of the year and takes place a few months before the Iowa caucus.

His speech will be in support of President Obamas reelection campaign.

“It’s an honor to welcome Mayor Emanuel to the state and give him an opportunity to speak to Iowa Democrats, state Democratic Party Chairwoman Sue Dvorsky said. “Through his service to both the Clinton and Obama White Houses, his leadership in Congress and now his vision for the city of Chicago, he has been one of the most dedicated and resonate voices in the Democratic Party.

It will be the second time Emanuel has helped out Obama’s reelection effort. In July, he was the speaker at a New York fundraiser for the Obama campaign.

Keynote speakers at the Iowa dinner usually have prominent national profiles. Past speakers include Vice President Biden, former President Bill Clinton and former Vice President Al Gore.

Obama spoke at the dinner during the 2008 presidential campaign, which helped boost his candidacy. He went on to win the 2008 Iowa caucus.
