O'Brien himself narrated a five-minute video recording in which he stated the "many, many concerns" of the Catholic Church concerning the bill which was to be voted on in Parliament. It was posted on YouTube, and sent as a DVD to every member of Parliament. In the video O'Brien made clear he was not against medical research, and supported research with non-embryonic stem cells, but was opposed to using embryos which would later be destroyed. He expressed the church's concerns over "human-animal hybrids".
