It surprises you that Republicans don’t investigate in good faith? Ken Starr was the Whitewater investigator who continued the investigation after the previous one left. He was appointed a year before Monica Lewinsky arrived at the White House.

This is why Clinton’s approval ratings went up after he was convicted of “perjury” for misleading an investigation into his private life. Should he have done it? No. Did the American public care? Hell no.

With the assistance of a family connection, Lewinsky secured an unpaid summer White House internship in the office of White House Chief of Staff Leon Panetta. Lewinsky moved to Washington, D.C. and took up the position in July 1995.

In August 1994, Republican Kenneth Starr[39] was appointed by a three-judge panel to continue the Whitewater investigation, replacing Republican Robert B. Fiske, who had been specially appointed by US attorney general Janet Reno, prior to the re-enactment of the Independent Counsel law.
