Was a key participant in the activities surrounding the Ken Starr investigation of Bill Clinton, representing David L. Hale, the Whitewater Independent Counsel's chief witness against Bill Clinton. Hale himself had earlier pled guilty to two felonies related to defrauding the Small Business Administration of more than $3.2 million through a federally subsidized company that he headed. Olson provided Hale counsel worth $140,000 without collecting the fees.
Olson was summoned to testify under oath before a congressional committee in March 1983 about advice which the Justice Department had given the EPA on the withholding of documents, related to the Reagan administration's sabotage of the enforcement of anti-pollution laws by the Environmental Protection Administration. An investigation into the activities of the EPA led to the forced resignation of EPA Administrator Ann Gorsuch and of Rita Lavelle, who was in charge of toxic waste cleanup for the agency. In 1986 the Reagan administration was compelled to appoint an independent counsel, Alexia Morrison, to determine whether charges should be brought against Olson for his role in covering up the EPA scandal. Olsonwon a decision from the US Court of Appeals for the District of Columbia that the Independent Counsel Act was unconstitutional, a decision written by Laurence Silberman, who served in the Nixon Justice Department and is another prominent member of the right-wing legal fraternity in Washington. In the midst of the incident, he left the Department of Justice and returned to Gibson Dunn & Crutcher (a law firm that represented Bush in the Florida election recount).
EDIT: more on his history of perjury: "He earned a full investigation by an independent counsel, for perjury and obstruction of justice, because of this testimony.
Olson was even cited for contempt of court while contesting the I.C. investigation -- a case he took all the way to the Supreme Court, where he lost decisively. However, he eventually avoided prosecution when the independent counsel scrupulously ruled that, though Olson's testimony was "misleading and disingenuous," it did not rise to the level of prosecutable perjury."

But the rest of the Shaheen report, which presumably details the unsavory activities of the Arkansas Project and its detectives, has remained under seal. Its contents may be of interest to Democrats on the Senate Judiciary Committee as they consider an Olson nomination."
