As you might expect, Fr. Pfleger, as the cardinal says, "does not believe this to be the right step at this time." Instead of balking, the lefty priest should be giving thanks that he is getting off lightly.
After all, he is not one of the orthodox, pro-Pope, pro-Magisterium, pro-life seminary applicants, seminarians and priests over the past several decades who have been denied entry to the seminary, denied ordination, exiled to isolated parishes or told to retire early, and on top of all that, ordered to submit to psychiatric evaluation so that would go on his permanent record.
Incidentally, a quick check of the website of the "Faith Community of St. Sabina" in Chicago (I knew they wouldn't call themselves a church or a parish) turns up no sign of a parish pro-life committee.
