A key Republican senator is demanding that the Department of Homeland Security provide details about the immigration status of two men, including one illegal immigrant, who have been charged with the murder of a California woman.

Senate Judiciary Committee Chairman Chuck Grassley, R-Iowa, said the murder of Marilyn Pharis on July 24 appears to be another example of how DHS is failing to do enough to ensure illegal alien criminals are removed from the country. Pharis’ death came just weeks after another illegal immigrant with a criminal record picked up a gun and fired it, killing Kate Steinle in San Francisco.
