Wisconsin U.S. Sen. Tammy Baldwin will headline the Minnesota DFL's Humphrey-Mondale fundraising dinner in April.

Baldwin is a high-profile freshman whose 2012 race against former Gov. Tommy Thomson, a Republican, garnered national attention.

The fundraising dinner will be on April 20 at the Minneapolis Convention Center.

It tends to be one of the DFL's single biggest fundraisers of the year.

The DFL landed former President Bill Clinton as its headliner last year, which helped it double its fundraising expectations. That one dinner, in August, brought in nearly $700,000 for the party.

The party's October fundraising dinner, featuring Mass. Gov. Deval Patrick, raised just under $90,000.

Like the Clinton fundraiser, this year's April fundraiser will not be open to the media.
