A GOP House floor leader is resigning from the Illinois House, citing “cyber security issues.”

Rep. Ron Sandack of Downers Grove issued a statement Sunday that said he began to “re-evaluate” his role “after some cyber security issues arose.”

Sandack also says in the statement released through a House GOP spokeswoman that he is no longer willing to miss important family events.

The statement says that Sandack’s resignation is effective immediately, but that he will work with his replacement to ensure he or she is successfully elected in November.

He narrowly won a primary fight in 2014 after he came out in favor of gay marriage. He has since become an ally of Gov. Bruce Rauner and a floor leader in the House. He was seeking re-election to a third term this fall.

Sandack regularly used Facebook and Twitter to communicate about local and state issues, but unexpectedly deleted his accounts last week.

Sandack could not immediately be reached by The Associated Press for further comment.
