Kathy Salvi will begin as chair July 19.
Tracy released a statement Friday, saying, "Congratulations to Kathy Salvi for taking on this challenging yet important position to build a brighter future for Illinois. Republicans in this state are united behind President Trump and understand that the Biden/Pritzker agenda is wrong for our families. We will show in Milwaukee this week that we are unified in purpose - to make this state and this country great once again with a message of hope and prosperity for the future."
The Republican National Convention is in Milwaukee next week.
Tracy took over the volunteer position in 2021.
Salvi, a lawyer and former assistant public defender, unsuccessfully ran against Sen. Tammy Duckworth in 2022.
She is from the northwest suburbs.
