New York City Mayor Bill de Blasio, who was just re-elected to his second term as mayor on November 7, is headed to Iowa, fueling speculation that he is seriously considering a run for president in 2020.

The Des Moines Register reported that de Blasio will be heading up a political fundraiser event on Dec. 19, at the Temple for the Performing Arts in Des Moines. He is to be the “featured guest” at a holiday party fundraiser for the organization, Progress Iowa. Tickets are being sold for $50 each for the event, which starts at 5:30 pm.

De Blasio, a Democrat, campaigned in Iowa for Hillary Clinton, knocking on doors in Des Moines, Indianola, Knoxville and Iowa City prior to the 2016 caucuses.

He also campaigned in Iowa for Clinton in 2008, and for John Edwards in 2004.

In advertising the fundraiser, Progress Iowa released the following statement from de Blasio:

“Iowans are speaking out and showing up to fight back against what conservatives are doing to their state and our country. Standing up for quality public education, access to health care, and to make sure working families get a fair shot matters in Iowa and New York, and I can’t wait to discuss those ideas as well as how we can work together when I visit in December.”
