State Sen. Jim Oberweis says he's gathering petition signatures to make a bid for the U.S. Senate.

The Republican from Sugar Grove made the comments Wednesday at a Springfield rally for opponents of same-sex marriage. He says he wants to challenge Democratic U.S. Sen. Dick Durbin.

Oberweis is a dairy magnate who has made numerous bids for office before.

He made previous unsuccessful attempts for U.S. Senate in 2002 and 2004. He also ran and lost in the 2006 Republican gubernatorial primary, and a congressional bid in 2008. He won a seat to the state Senate last November.
 
Downers Grove businessman Doug Truax and Kane County Regional School board member Chad Koppie are also making primary bids.
