Cardinal Burke was among those elected by his fellow bishops of one of the three English-speaking circles (the Anglicus A) as moderatore (chairman) of the group to help in the writing of the group reports that make the final report. There were many "conservatives" elected in the different groups, including Cardinal Sarah, moderator for Gallicus (French-speaking) A, Abp. Léonard, relatore (rapporteur) for Gallicus B; Cardinal Bagnasco, moderator for Italicus B; Cardinal Robles Ortega, moderator for Ibericus (Spanish-speaking) A.A translation of the Italian transcript is provided by Rorate Caeli (October 11, 2014), including the above-cited commentary.
So, what was the Pope's response to these surprising votes?
He personally appointed ad hoc, and without prior announcement on this before the synod, six other prelates for the composition of the final report (the "Relatio Synodi"), all known as strong liberals: Cardinals Ravasi and Wuerl, Abps. Victor Manuel Fernández, Aguiar Retes, and Bp. Peter Kang, and the Superior General of the Society of Jesus Fr. Adolfo Nicolás Pachon.

Z describes as "the video interview that has sent a few of the catholic Left to swoon upon their feinting couches, others to beat the air vainly as so many windmills, others to erupt in spittle-flecked nutties."
