Francisco sanchez, the convicted felon who federal Officials Say had been deported five times to mexico today in a jailhouse interview said he agreed with police that he shot and killed the 32yearold and doesnt remember everything. The only thing i can tell you is that i claim responsibility, he said. The shooting has ignited criticism of San Franciscos policy as a socalled sanctuary city that gives some protection to undocumented immigrants by barring authorities from asking about their immigration status. After being picked up for a drug warrant last march the department of Homeland Security says sanchez should have been turned over to federal immigration officials. Instead he was set free. Seizing the divisive issue of undocumented immigrants again today, donald trump who earlier tweeted his heartfelt condolences to the steinle family. Trumps words driving a wedge in a crowded republican field desperate to win latino voters. In a newly released statement he said the Mexican Government is forcing their most unwanted people into the United States.

You have a big chunk of the party, leaders that i talked to associated both with president ials and nonpresident ials that say you know what this is going to burn itself out, this is like herman cain and 999 from four years ago. A year from now we wont be talking about it. There are other republicans who are worried that donald trump is going to be the new todd akin.
