The federal bureaucrat who blocked armed law enforcement agents from apprehending a man involved in the San Bernardino terror attack last December, then allegedly lied to investigators about her actions, has been reassigned to another post, but likely won’t face further investigation, FoxNews.com has learned.

The U.S. Citizenship and Immigration Services supervisor who an Inspector General’s report did not name but blasted for keeping Department of Homeland Security agents from Enrique Marquez is Irene Martin, who, according to her Linkedin.com account, has been with the agency for at least 16 years, 13 years as a field supervisor.

Marquez and his Russian wife Mariya Chernykh were scheduled for an interview with Martin’s staff on Dec. 3, the day after Marquez’s friend Syed Rizwan Farook and his wife, Tashfeen Malik, killed 14 people at an office Christmas party. After the FBI learned Marquez allegedly supplied the guns, they sent five armed Homeland Security Investigation agents to the USCIS building to detain Marquez.

…Martin, who formally oversaw San Bernardino and Riverside as well as Los Angeles counties, did not return emails to FoxNews.com. USCIS in California referred calls to its Washington headquarters, where officials refused to comment. However, experts and former law enforcement agents told FoxNews.com Martin’s actions amounted to obstruction of justice.

“The USCIS field director’s behavior was not only outrageous and reprehensible, but in violation of federal law and policy that ensure any law enforcement agency the ability to make arrests or conduct interviews in government facilities,” said Jessica Vaughan, of the Center for Immigration Studies, a Washington-based research institute. “I cannot imagine any possible excuse for her actions, and it is doubly concerning that she apparently lied to the investigators about what she did. She needs to be fired, not to mention prosecuted.”

Although Marquez was only a “person of interest” a day after the attack, authorities were frantically trying to track down anyone associated with Farook and Malik. Both Farook and Malik were killed by law enforcement after their morning attack.

“When agents show up to CIS for a criminal investigation, they should never be impeded. That is obstruction of justice,” said Claude Arnold, retired special agent in charge for ICE’s Los Angeles bureau of Homeland Security Investigations.
