SPRINGFIELD, Ill. (AP) — Republican Bruce Rauner (ROW’-nur) will not say whether he believes it’s fair that as a wealthy businessman, he was able to avoid paying Social Security and Medicare taxes in 2010 and 2011.

The candidate for Illinois governor was asked Friday about a Chicago Tribune report last week. It showed business income-loss tax rules allowed Rauner to pay no Social Security or Medicare taxes in those years despite income of $55 million.
