Tucker succeeded former President Clinton as governor of Arkansas, but was forced to resign after convictions in the Whitewater investigation.
Clinton gave up his Arkansas law license for five years as part of a deal with Whitewater independent counsel Robert Ray in exchange for Ray's dropping the investigation into the president's liaison with former White House intern Monica Lewinsky. Clinton was disbarred from the Supreme Court, as part of an automatic procedure, earlier this term.
Tucker lost his license to practice law in Arkansas last fall as a result of his Whitewater convictions, but served time in house arrest because of his health problems.
He was convicted in 1996 of mail fraud and conspiracy to defraud the government -- basically overstating his assets to secure a loan -- in an investigation that grew out of, but had nothing to do with, Ray's investigation of Clinton's business dealings.
Clinton was never charged in Whitewater, despite the $60 million investigation.
The president was impeached for allegedly lying under oath about his relationship with Lewinsky, but was acquitted by the Senate.
Tucker had to resign as Arkansas governor following the 1996 convictions, and in 1998 pleaded guilty to a separate charge of conspiring to defraud the Internal Revenue Service.
