It just keeps looking worse and worse:

When federal prosecutors and agents learned the true extent of the releases, many were shocked and angry. Some had spent years, if not decades, working to penetrate the global proliferation networks that allowed Iranian arms traders both to obtain crucial materials for Tehran’s illicit nuclear and ballistic missile programs and, in some cases, to provide dangerous materials to other countries.

“They didn’t just dismiss a bunch of innocent business guys,” said one former federal law enforcement supervisor centrally involved in the hunt for Iranian arms traffickers and nuclear smugglers. “And then they didn’t give a full story of it.”

In its determination to win support for the nuclear deal and prisoner swap from Tehran — and from Congress and the American people — the Obama administration did a lot more than just downplay the threats posed by the men it let off the hook, according to POLITICO’s findings.

Through action in some cases and inaction in others, the White House derailed its own much-touted National Counterproliferation Initiative at a time when it was making unprecedented headway in thwarting Iran’s proliferation networks. In addition, the POLITICO investigation found that Justice and State Department officials denied or delayed requests from prosecutors and agents to lure some key Iranian fugitives to friendly countries so they could be arrested. Similarly, Justice and State, at times in consultation with the White House, slowed down efforts to extradite some suspects already in custody overseas, according to current and former officials and others involved in the counterproliferation effort.

And as far back as the fall of 2014, Obama administration officials began slow-walking some significant investigations and prosecutions of Iranian procurement networks operating in the U.S. These previously undisclosed findings are based on interviews with key participants at all levels of government and an extensive review of court records and other documents.

“Clearly, there was an embargo on any Iranian cases,” according to the former federal supervisor.

It was treasonous, really, and probably at the instigation of Valerie Jarrett.
