It is not lost on anyone that this is taking place well after it could do any significant damage to the Obama administration.

The release of the documents was ordered by a US District Court Judge Amy Berman Jackson on January 19th, ending a long saga that actually saw the House vote then Attorney General Eric Holder in contempt of congress for withholding requested information. Of course the DOJ decided not to prosecute itself on that matter. 

As Politico reports, Justice Department spokesman Patrick Rodenbush confirmed that the administration does not plan to appeal. He argued that Jackson's ruling validated Obama's initial claim of privilege. As a reminder, Obama's privilege claim was broad-ranging, seeking to cover not only internal deliberations about how to respond to congressional inquiries but also discussions about media strategy related to the congressional probes.
