In response to a Freedom of Information Act request, Bill Clinton's presidential library will release nearly 500 pages of records related to Donald Trump and the Trump Organization, according to the National Archives.

"The Clinton Presidential records proposed for opening consist of email concerning birthday notes sent from President Clinton to Mr. Trump. Email also includes references to his campaign for President in 1999," a National Archives notice from Jan. 14 reads.

The 464 pages of documents could resurface questions about Trump's once-friendly relationship with the political couple -- an association from which the current GOP frontrunner has tried hard to distance himself.

Earlier this month, Trump launched a series of personal attacks against the Clintons while on the campaign trail, even comparing the former president's sexual history to that of Bill Cosby's, the sitcom star recently charged with sexual assault allegations.

Other entries in the presidential library database include "a photograph of President Clinton with Donald Trump at Trump Towers in New York, an autographed copy of Mr. Trump's book The Art of the Deal, and briefing materials for press events that include media questions about Mr. Trump's possible run for the presidency in 2000."

The Clinton library is set to release the documents on April 11, 2016, provided the former or current presidents do not request a delay.
