SCANDAL: Fugitive financier Marc Rich was indicted for racketeering, fraud, tax evasion and illegal oil trading with Iran, but Bill Clinton pardoned him on his last day in the White House

The FBI on Monday released 129 pages of documents related to former president Bill Clinton's lame-duck pardon of a fugitive financier whose family contributed $450,000 to help build his presidential library and millions more to other Democratic Party causes.

Rich's wife Denise also contributed $100,000 to Hillary Clinton's 2000 Senate campaign as the first family prepared to clear out of the White House.

The disclosures will prove embarrassing to the former first family as Hillary Clinton tries to avoid a career-ending defeat next Tuesday at the hands of Donald Trump.

The FBI investigated the case of Marc Rich, who died in 2013, more than a decade ago, assigning it to the ominous sounding 'Public Corruption Unit.'

The documents released Monday leave much to the imagination, mostly redacted by government lawyers for privacy reasons and to preserve the secrecy of a federal Grand Jury.

But merely bringing the episode back up so close to Election Day has put an old Clinton black eye back on the front burner.

CLOSING DAYS President Clinton had fewer than 50 days left in office when Mrs. Rich presented him with this saxophone as a gift during a charity gala in New York City

Rich, a legendary oil commodities and hedge-fund trader in his day, was charged with multiple counts of tax evasion, wire fraud, racketeering, and cutting petroleum deals with Iran during the 1979 hostage crisis.

Rich was in Switzerland when he was indicted, and never returned to the United States. He hired Jack Quinn, a former White House counsel to Clinton, as his lawyer.

His wife later renounced her U.S. citizenship and moved to Austria where she already had dual citizenship – saving herself tens of millions of dollars in taxes.

Rich passed away in 2013 and was laid to rest in Tel Aviv.

Pardoning Rich on his last day in office turned out to be one of Bill Clinton's most controversial acts of president.

The FBI concluded that Clinton did not follow established procedures when he finalized the pardon, and only informed one person at the Department of Justice that Rich had sought the pardon: future Obama administration attorney general Eric Holder.

FBI director James Comey, then a federal prosecutor, ran the investigation into the Rich pardon. He criticized Holder's involvement in the controversy, calling the pardon 'a huge misjudgment.'

But he never recommended criminal charges against anyone embroiled in the scandal.

HILLBLAZER: Mrs. Rich gave Hillary Clinton $100,000 in 2000 for her U.S. Senate campaign as her time as America's first lady as coming to a close

SALAD DAYS: Marc and Denise Rich were already among the world's financial elites in the mid-1980s, partially because Mr. Rich was trading oil in Iran in violation of a U.S. embargo

Final resting spot: Denise at her husband's funeral in Tel Aviv in 2013

The bureau said Tuesday that there was no political purpose in releasing the documents a week before a presidential election, calling the timing an unavoidable coincidence.

'The FBI's Records Management Division receives thousands of FOIA requests annually which are processed on a first in, first out (FIFO) basis,' the bureau said, referring to the Freedom Of Information Act.

'By law, FOIA materials that have been requested three or more times are posted electronically to the FBI's public reading room shortly after they are processed.

'Per the standard procedure for FOIA, these materials became available for release and were posted automatically and electronically to the FBI's public reading room in accordance with the law and established procedures.'

Good friends: Denise's best friend Ivana Trump and her daughter Ivanka attended a party on the yacht in 2006

Hillary Clinton campaign spokesman Brian Fallon slammed the FBI on Tuesday for releasing the pages related to the Rich pardon.

Absent a FOIA litigation deadline, this is odd. Will FBI be posting docs on Trump's housing discrimination in '70s?' he tweeted.

Denise Rich also has incredibly close ties to the Trump family, and is best friends with the billionaire businessman's first wife Ivana.

She was even one of the bridesmaids at Ivana's wedding to Rossano Rubicondi in 2008 at Mar-a-Lago, Donald's massive Palm Beach estate.

Ivana is also a frequent guest on Denise's yacht Lady Joy, which she uses to host a party every year during the Cannes Film Festival.
