CHICAGO (CBS) — Young opponents of abortion gathered outside the Thompson Center to denounce Gov. Bruce Rauner and the new law he signed this week that provides for taxpayer financing of abortion.

GOP politicians called Rauner’s decision “political suicide.” One ally called  him “Benedict Rauner” in a Facebook post. The governor agreed to be scratched from a southwest suburban GOP picnic.

After he told Cardinal (Blase Cupich) one thing and then did something else,” said McConchie. That is not leadership. That is not the courageous leadership that we need to have in our state.”
