In 1944, Cawthorn did not seek re-election to the state Senate but instead ran a strong though unsuccessful race for attorney general of Louisiana against fellow Democrat [[Fred S. LeBlanc]] of [[Baton Rouge]], who carried the backing of the successful gubernatorial nominee, [[Jimmie Davis]]. Known for his singing career too, Davis was elected that year to the first of his two non-consecutive gubernatorial terms.

In May 1946, Cawthorn was convicted in the United States District Court for the Eastern District of Louisiana for his role as the attorney in an [[income tax]] evasion and jury tampering case against businessman William T. Burton, former Governor Noe, and Marcel F. La Branche, a juror. Cawthorn, Burton, and La Branche were found guilty and each sentenced to two years in prison and fined $10,000, but Noe was acquitted. The three lost their appeals before the United States Court of Appeals for the Fifth Circuit in [[New Orleans]]. As a result of his conviction, Cawthorn was disbarred.<ref>{{cite web|url=http://leagle.com/decision/195323267So2d165_1215.xml/LOUISIANA%20STATE%20BAR%20ASS'N%20v.%20CAWTHORN|title=Louisiana State Bar Association v.
