A California camp counselor — now charged with child molestation and distribution of child pornography— was able to maintain his Deferred Action for Childhood Arrivals (DACA) status and job prior to his arrest despite being considered a “potentially egregious public safety,” the Obama administration has revealed to Senate Judiciary Committee Chairman Chuck Grassley (R-IA).

In response to questions from Grassley earlier this year, U.S. Citizenship and Immigration Services confirm that the camp counselor charged with child molestation, Edgar Covarrubias-Padilla, received DACA status on May 22, 2013. Immigration and Customs Enforcement was aware that he was under investigation for child molestation November 17, 2014, according to Grassley’s office.

USCIS, however, was not aware of the investigation until March 31, 2015, despite the fact that USCIS said ICE “typically apprise[s] USCIS when a recipient of DACA or an immigration benefit is an investigative target.”

Covarrubias-Padilla’s DACA status was terminated six days after his arrest on May 13, 2015

In a letter to DHS Sec. Jeh Johnson dated Thursday, Grassley presses for more details on how Covarrubias-Padilla slipped though the cracks.

“Although the Director’s response letter states that “ICE field offices typically apprise USCIS when a recipient of DACA or an immigration benefit is an investigative target,” in this case, USCIS failed to learn of the investigation until months later on March 31, 2015,” Grassley writes.

“Despite both components’ knowledge of Covarrubias-Padilla’s investigation by March of 2015, and a referral to the Background Check Unit (BCU) as a “potentially egregious public safety case,” the revocation of DACA did not occur until May, 13, 2015, several days after his arrest,” he added.
