Fitzgerald released a statement Monday saying he won't rule out a run for higher office in the future. But he said he plans to return next session as majority leader.
The statement by the Juneau Republican dispelled rumors that Fitzgerald would enter the fray of what will likely be a busy primary to fill Petri's seat.
State Sen. Glenn Grothman, a West Bend Republican, has announced he will move into the 6th Congressional District to run. Rep. Duey Stroebel, a Saukville Republican also plans on running. Republican Sen. Joe Leibham said he is also thinking about running.
Petri, a Republican, has represented Wisconsin since 1979.
