A lean, intense Dallas lawyer, Campbell, 47, breathed new fire into Paula Jones's sexual harassment suit against President Clinton after he took over the case last fall.

Campbell's staff of attorneys and investigators took a messy lawsuit and turned it into a grave presidential crisis – in large part by finding former intern Monica Lewinsky and subpoenaing her, and several other women, as part of an attempt to show that the president has a habit of sexual relationships with people who work for him.

On January 16, one of Campbell's colleagues secretly met with Lewinksy's confidante, Linda Tripp, who briefed them about Lewinsky's purported affair, allowing them to ask Clinton detailed questions during his deposition the following day.

And in an extraordinary series of March filings, ostensibly in response to opposing counsel Robert Bennett's motion to have the case dismissed, Campbell introduced testimony about a slew of sordid sexual encounters allegedly involving Clinton.

On April 1, Campbell lost big, when Susan Webber Wright tossed the case out, saying it was groundless.

Campbell's work has been partly financed by John W. Whitehead's Rutherford Institute.
