U.S. Department of Health and Human Services (HHS) reports reveal that nearly 1,000 criminal incidents involving unaccompanied alien children (UAC) occurred during the Obama administration, Judicial Watch said Tuesday.

“The Obama administration presided over a humanitarian and public-safety nightmare in its handling of ‘unaccompanied alien children,'” Judicial Watch President Tom Fitton said in a statement. “The incident reports also support the Trump administration’s contention that the UAC crisis, which continues, includes murderers, rapists, drug smugglers, and human traffickers’ being routinely allowed into the United States.”

The U.S. is currently embroiled in controversy over Trump’s zero-tolerance immigration enforcement policy, which separated illegal immigrant children from their parents at the border. Administration officials are scrambling to reunite the children with their parents ahead of the initial Tuesday deadline.

Judicial Watch released 224 pages of summaries of significant incident reports (SIRs) revealing that the Obama administration allowed UACs to remain in the country who admitted “to murder, belonging to MS-13, [or] threatening others with rape,” along with “drug smuggling, molesting other UACs, and seriously assaulting other UACs or staff.”

In one incident, a male UAC said he was “forced to kill” for the Gulf Cartel, a criminal syndicate and drug-trafficking organization in Mexico. Another male said he was part of the MS-13 gang for a year prior to entering the U.S. illegally.

One male threatened to rape another UAC, saying, “I am a rapist. I am going to rape you,” according to the incident reports.

Judicial Watch obtained the report summaries from the HHS Administration for Children and Families’ Office of Refugee Resettlement (ORR) more than three years after the watchdog organization filed its Freedom of Information Act (FOIA) request. Judicial Watch sought documents from the key six-month period in 2014 when a huge wave of UACs swarmed the border.

The FOIA request sought “any and all” SIRS, and also SIR addenda, including medical SIRs, both emergency and nonemergency, submitted to the ORR for UACs from May 1, 2014 to the present.

Judicial Watch also requested “any and all summary reports, which are derived from or based upon data contained in the SIRs, including daily, weekly, monthly or year-to-date reports, that were prepared by, provided to, or are in the possession of the ORR.”

Judicial Watch ultimately found that the ORR received 24,680 SIRs in fiscal year 2014.

Other SIRs included accounts of UACs being raped or assaulted on their journey to the U.S. border or by government contractors while in the U.S., along with cases of self-harm.
