Rove some more free air time instead of asking him about this (the post is from Nov. 2012): Watchdog: Karl Rove And His Crossroads GPS Broke Election Law By Failing To Disclose Donors:

The non-partisan Citizens for Responsibility and Ethics in Washington (CREW) filed complaints Thursday with both the Federal Election Commission (FEC) and the Federal Bureau of Investigation (FBI) alleging that Karl Rove and his secretive Crossroads GPS violated election law and may have engaged in a criminal conspiracy to do so.

Under campaign finance law and FEC regulations, 501(c)(4) groups, like Crossroads GPS, can raise unlimited funds from wealthy individuals and corporations without having to disclose their donors. The only time donors to these secretive groups must be disclosed is when donors give more than $200 explicitly “for the purpose of furthering an independent expenditure.”

As they went onto explain, that's not what Rove's group was doing. Rove loves to go on the air and pretend like he's the victim here when the truth is far from it. As Bold Progressives asked in the banner below, the real question is why did the IRS ignore massive political players and go after only the smaller groups instead? The likely answer is they didn't want to take on their lawyers at the places with the real money, and so they took the easy way out instead, but if that's the case, it's no excuse.

One thing you can be sure of though is you won't see Rove asked about any of this on the air. He'll stay away from the few shows and hosts that would actually ask him about it and none of them are on Fox.
