A terrible double standard has been uncovered within the media, and it centers on one of the left’s favorite talking points: Illegal immigration.

The topic has dominated headlines lately sparking what seems like coordinated outrage among liberals. Apparently oblivious to the fact that the Obama administration detained minors at the border for years, the left has pointed fingers instead at President Donald Trump for enforcing regulations that were enacted before he was even president.

According to The Washington Post, the Obama administration failed to protect thousands of Central American children who have flooded across the U.S. border since 2011, leaving them vulnerable to traffickers and to abuses at the hands of government-approved caretakers, a Senate investigation has found.

The Office of Refugee Resettlement, an agency of the Department of Health and Human Services, failed to do proper background checks of adults who claimed the children, allowed sponsors to take custody of multiple unrelated children, and regularly placed children in homes without visiting the locations, according to a 56-page investigative report released Thursday.

And once the children left federally funded shelters, the report said, the agency permitted their adult sponsors to prevent caseworkers from providing them post-release services.

Sen. Rob Portman (R-Ohio) initiated the six-month investigation after several Guatemalan teens were found in a dilapidated trailer park near Marion, Ohio, where they were being held captive by traffickers and forced to work at a local egg farm. According to The Western Journal, the boys were among more than 125,000 unaccompanied minors who have surged into the United States since 2011, fleeing violence and unrest in Guatemala, Honduras and El Salvador.

Another Guatemalan was placed with a sponsor who forced him to work at least 12 hours a day to pay off a $6,500 smuggling debt, which the sponsor later increased to $10,900, according to the report.

A boy from El Salvador was permitted to live with his abusive father, despite warning caseworkers that his father regularly hitting him with an electrical cord, the Gateway Pundit reported. When the boy alerted authorities that his father forced him to work all day, a post-release case worker found him starving, malnourished and imprisoned in a basement.

“It is intolerable that human trafficking — modern-day slavery — could occur in our own backyard,” Portman said in a written statement. “What makes the Marion cases even more alarming is that a U.S. government agency was responsible for delivering some of the victims into the hands of their abusers.”

The report concluded that administration “policies and procedures were inadequate to protect the children in the agency’s care.”

HHS spokesman Mark Weber said in a statement that the agency would “review the committee’s findings carefully and continue to work to ensure the best care for the children we serve.”

The report was released ahead of a hearing Thursday before the Senate Permanent Subcommittee on Investigations, which Portman co-chairs with Sen. Claire McCaskill (D-Mo.). It detailed nearly 30 cases where unaccompanied children had been trafficked after federal officials released them to sponsors or where there were “serious trafficking indicators.”
