Senate Judiciary Committee Chairman Charles E. Grassley, said he’ll convene a hearing July 21 to hear from the victims themselves, saying it’s an area Democrats ignored when they held power in Congress.

“This hearing is intended to highlight how misguided the Obama administration’s lax enforcement policies are and how these policies are putting Americans in harm’s way,” the Iowa Republican said.

The senator has also asked the chiefs of two immigration agencies to testify. One of those, Immigration and Customs Enforcement Director Sarah Saldana, is likely to face the stiffest questions after an illegal immigrant her agency had been trying to deport was accused of a murder in San Francisco earlier this month.
