From this:

Harold Hurtt, a former police chief in Houston and Phoenix, has been hired as the director for the U.S. Immigration and Customs Enforcement's Office of State and Local Coordination. Starting July 6, Hurtt will supervise outreach and communication between ICE, local law enforcement agencies, tribal leaders and representatives from non-governmental organizations...

...as a police chief, Hurtt was a supporter of (sanctuary cities) policies, by which illegal immigrants who don't commit crimes can live without fear of exposure or detainment because police don't check for immigration papers.

He also, during his tenure as Houston police chief, criticized ICE's key program (287g) that draws on local law enforcement's support.

At the link, ICE chief John Morton praises him, and it's pointed out that he supports the jail-side part of 287g, even if he doesn't support the sweeps part (as practiced by Joe Arpaio).

Hurtt was mentioned here in 2005's "Houston reaffirms illegal aliens sanctuary policy". As I said in that post, 9/11 Commission member John Lehman said in 2004:

"The terrorists know" which cities have such policies.
