(CNSNews.com) -- Judicial Watch announced on June 19 that the National Security Council has revealed that documents regarding the unmasking by President Barack Obama’s National Security Advisor Susan Rice of “the identities of any U.S. citizens associated with the Trump presidential campaign or transition team” have been removed to the Obama Library.

Such documents, by law, cannot be released to the public for at least five years, and after that the library may still erect hurdles to access them. In effect, documents reportedly related to Congress’ investigation of Russia collusion in the 2016 election are now sealed, including materials gathered by the Obama administration in 2015-16 and perhaps earlier.

On April 4, Judicial Watch requested the records – through the Freedom of Information Act -- containing information regarding people “who were identified pursuant to intelligence collection activities,” but the National Security Council (NSC) refused to fulfill this request.

The NSC also informed Judicial Watch that it would not be turning over communications with any Intelligence Community member or agency regarding the alleged Russian involvement in the 2016 presidential election, the hacking of Democratic National Committee computers, or the any suspected communication between Russia and the Trump campaign or transition officials.

“Documents from the Obama administration have been transferred to the Barack Obama Presidential Library. You may send your request to the Obama Library,” the NSC stated to Judicial Watch. “However, you should be aware that under the Presidential Records Act, Presidential records remain closed to the public for five years after an administration has left office.”

“Prosecutors, Congress, and the public will want to know when the National Security Council shipped off the records about potential intelligence abuses by Susan Rice and others in the Obama White House to the memory hole of the Obama Presidential Library,” Judicial Watch President Tom Fitton said in light of the NSC’s decision to withhold these records.

“We are considering our legal options but we hope that the Special Counsel and Congress also consider their options and get these records,” said Fitton.
