Donald Trump Featured in New Batch of Bill Clinton Documents

— -- It's no secret that Donald Trump and former President Bill Clinton have talked privately in the past, but the public will now get a closer look at their correspondence with the pending release of documents from Clinton's presidency.

The Clinton Presidential Library will soon release 464 pages of material related to Trump and his organization following a Freedom of Information Act (FOIA) request, according to an official notice from the National Archives.

The documents include the run-of-the-mill items such as Trump's invitations to the White House, a photo of Clinton and Trump at Trump Tower and an autographed copy of Trump's book “The Art of the Deal.”

But the release also includes "references to [Trump's] campaign for President in 1999," which could prove to produce some ammunition for Trump's GOP rivals eager to capitalize on his past coziness with the Clintons.

It was revealed in August that Bill Clinton and Trump held a private phone conversation just weeks prior to Trump's announcement of his candidacy, raising eyebrows across the jittery Republican field.

The White House or Clinton’s office has until April 11 to have the documents released, ask for a 30-day extension or claim executive privilege. Upon their release, the Clinton Library will have them available at its location in Little Rock, Arkansas, and they will be available online a few weeks after the physical release.
