Vatican opens archive on WWII pope Pius XII

Pope Francis says the Catholic Church will open up its archives on Pius XII - the Pope during World War Two. Although supporters say he secretly worked to help the victims of the Nazis, he has been widely accused of staying silent on the Holocaust. Now Pope Francis has agreed to unlock the Vatican's archives from Pius' era even though the Vatican usually waits 70 years. Joining us now from Rome is our correspondent John Allen.
