Biden appeared on meet the press, just a few weeks after Nancy Pelosi did, and offered an almost identical reason for his support of abortion. The US Bishops have already started to respond. This one is not going away soon.
Here is the video below.
Here is the homily (audio) by Bishop Robert Morlino, who responded to the statements. You can tell he was somewhat worked up. As he says, he is not addressing Democrats, he is addressing Catholics. Morlino takes it to them in plain English - great homily!
Biden should have kept his mouth shut. He doesn't know what he is talking about, the same goes for Pelosi.
