State Rep. Ron Sandack, a Downers Grove Republican and vocal legislative ally of Gov. Bruce Rauner, is resigning from the Illinois House after saying he’s had “cyber security issues” in recent days.

Sandack had been facing a re-election race in November and is well known in Illinois politics for his heavy use of Twitter and Facebook, as well as his role as a floor leader for Republicans in the Illinois House.

Sandack did not return requests for comment Sunday evening. But Illinois House Republicans provided a statement Sandack sent to political blog Capitol Fax, which broke the news.

* I talked to Sandack Sunday, so subscribers know lots more. Here’s the full statement…

It has been a tremendous honor and privilege to serve the people of the 81st district for the past four years in Springfield. But after some cyber security issues arose, I began to re-evaluate my continued public service.

I have always recognized there is no greater privilege than being a father and husband. My duties in Springfield has meant missing a lot of events in the lives of my children. I am no longer willing to miss important family events.

Therefore, I decided to resign from my seat effective today. I will work with my Republican replacement to ensure that she or he is successfully elected to the seat next November.

*** UPDATE 1 ***  From the House GOP…

“Ron Sandack is a dedicated and caring public servant. I want to thank him for his service to his constituents and the entire State of Illinois. I wish him well in his future endeavors,” said House Republican Leader Jim Durkin.

*** UPDATE 2 *** Durkin also sent this to his caucus members…

I spoke with Ron yesterday afternoon and respect his decision to resign. I am grateful for the work he has done collectively on behalf of our caucus and for his constituents. He will be missed.
