He has been known for slamming Hillary Clinton throughout the election over emails she deleted from a private server she used while serving as Secretary of State, but Donald Trump has his own history of deleting pertinent items and making documents seen as evidence in court cases against him completely disappear.

While Clinton has maintained that the 33,000 emails she deleted from the server ahead of the FBI investigation into her were all private, and has encouraged any findings from the probe recently resurfacing as authorities investigate Anthony Weiner to be made public to continue proving her innocence, Trump has long had a history of trying to hide documents and emails which have been subpoenaed in the various court cases brought against him and his companies over the years, according to a Newsweek investigation.

The investigation looks into several huge court cases filed against Trump, his family, and their companies since the 1970s, and uncovered that in each court case, that the strategy put forth by the now GOP candidate was to "deny, impede and delay" for cases-all while destroying documents that had been ordered to be handed over by the courts. Over the span of decades, the companies have destoryed or hidden thousands of emails, digital record and paper documents in defiance of court orders, and put up numerous hurdles which forced litigation to drag on for years, and occasionally forcing opponents to spend huge sums of money in legal fees as a result, leading to cases sometimes being settled simply to end the process.

Among the cases mentioned in the review are the charges that he and his father refused to rent apartments to African-Americans back in the 1970s. After delaying the investigation several times, Trump, while subpoenaed, appeared for a short deposition where he admitted that his family had been destroying corporate records for six months and there was no way to retain the documents because they had no program which would do so, in an attempt to "save space." The government was then granted access to the offices to find the records themselves, and they notified the company in six different attempts of the date they would be arriving, but were refused access during the inspection.

After more delays, a settlement was reached 18 months later despite relevant records being withheld, which ordered the Trumps to comply with federal housing regulations against discrimination, among other requirements, which were still ignored by the family, and after the government proved the claims, another complaint was brought against the family in 1978, and a new settlement was reached.

Similar tactics were used in cases against Trump in Fort Lauderdale, Fla. Back in 2009, and again in a separate case in 2005.
