i woululd like to start with miguel andrade.t is it precisely philadelphia promising to do in terms of creating sanctuary city? >> thank you so much for having me. basically, what philadelphia stands for is the fourth of them is that he is our mayor must recently announced, is that a sickly immigration and local law enforcement will no longer be working in conjunction. what was happening before with dust was if someone was undocumented in connection with local law enforcement, they were handing them over to immigration, to ice. basically what the community worked for and fought for in so many localities around the country was that we wanted to break that tie because we were seeing there was a lot of fear and mistrust from immigrant communities to local law enforcement and people were not coming forward and reporting when they were victims of crime or when they were witnesses to a crime. what sanctuary city is, or a fourth amendment city, basically, a city will not hand over somebody who is undocumented over to immigration unless
