State Sen. Jim Oberweis defeated Doug Truax in Tuesday's Republican Senate primary in Illinois, the Associated Press reports.
Oberweis, who was elected to the state Senate in 2012, will challenge incumbent Sen. Dick Durbin (D-Ill.) in November's general election. Durbin has held the seat since 2007.

A state legislator and dairy magnate has defeated a suburban Chicago businessman in the Republican primary for U.S. Senate in Illinois.
State Sen. Jim Oberweis' victory Tuesday over Doug Truax sends him on to a November matchup with Democrat Dick Durbin, the No. 2 Democrat in the Senate.
Oberweis is from the western Chicago suburb of Sugar Grove. He was elected to the Illinois Senate in 2012 and had made previous unsuccessful runs for U.S. Senate and governor.
He has been criticized for some political ads, including one before a previous election in which he said the number of immigrants entering the U.S. illegally each week could fill Soldier Field.
Truax has never held political office but had support from former U.S. House Speaker Newt Gingrich.
