In April 1996, Lewinsky's superiors transferred her from the White House to the Pentagon because they felt that she was spending too much time around Clinton. At the Pentagon, she worked as an assistant to chief Pentagon spokesman Kenneth Bacon. Lewinsky told co-worker Linda Tripp about her relationship with Clinton, and Tripp began secretly recording their telephone conversations beginning in September 1997. Lewinsky left the Pentagon position in December 1997. Lewinsky submitted an affidavit in the Paula Jones case in January 1998 denying any physical relationship with Clinton, and she attempted to persuade Tripp to lie under oath in that case. Tripp gave the tapes to Independent Counsel Kenneth Starr, adding to his on-going investigation into the Whitewater controversy. Starr then broadened his investigation beyond the Arkansas land use deal to include Lewinsky, Clinton, and others for possible perjury and subornation of perjury in the Jones case. Tripp reported the taped conversations to literary agent Lucianne Goldberg. She also convinced Lewinsky to save the gifts that Clinton had given her during their relationship and not to dry clean a blue dress that was stained with Clinton's semen. Under oath, Clinton denied having had "a sexual affair", "sexual relations", or "a sexual relationship" with Lewinsky.
