A group called Organizing For Action-Illinois plans a Saturday demonstration in Federal Plaza that's not the usual protest held at Adams and Dearborn.
It's a thank you, the group says, to U.S. Sen. Mark Kirk (R-Ill.), one of only four Republicans to vote for background checks legislation that ultimately failed.
"The group intends to let the Senator know that his constituents support him in standing up to powerful special interests and that they appreciate his strong stance in favor of universal background checks," a statement from the group reads. "This event is just one of dozens occurring nationally, specifically targeting Senators who crossed partisan lines to do the right thing. State groups from all across the country are thanking or shaming their Senators on this day."
