MILWAUKEE (CBS 58) -- More than 20,000 people are in Milwaukee this weekend for the annual LULAC convention.

The event kicked off Wednesday, with leaders laying out what they hope to accomplish with the four day event.

The annual event has a clear focus this week, and comes at a time when presidential candidates and the President himself are visiting the city.

The conference kicked off with a festive event at Potawatomi Casino.

The governor and mayor spoke, along with former Vice President Joe Biden's wife, Jill Biden.

The LULAC President says while immigration is in the headlines every day, there are two other important issues they want to tackle this week.

"Locally, we want to make sure that people have decent housing, good health care, we want to have good education for families -- so those are issues that are all LULAC issues as well," Mayor Tom Barrett said. 

Candidates Bernie Sanders, Elizabeth Warren, Julian Castro, and Beto O'Rourke will take place in a Presidential Town Hall Thursday.

The President will be in town for an unrelated visit on Friday.
