The first casualties of the looming government shutdown in Washington might be Minnesota GOP House candidates in 2014 who were to have a fundraiser Sunday featuring U.S. Rep. Darrell Issa, the California Republican who chairs the House Oversight and Government Reform Committee.

With the House likely to stay in session over the weekend to deal with a potentially climactic vote to keep the lights on in Washington, the event has been postponed.

Issa, the face of the House Republicans on Benghazi and other administration controversies, was to have been the keynote speaker at the event at the Lafayette Club in Minnetonka Beach.

The $100-$1,000 event also featured "special guest" U.S. Rep. Erik Paulsen, R-Minn., and GOP candidates for the U.S. Senate, governor, and Hennepin County Sheriff, according to an invitation obtained by the Star Tribune.
