LITTLE ROCK, Ark. — A jury convicted former Arkansas Treasurer Martha Shoffner of federal bribery and extortion charges Tuesday, saying her acceptance of $36,000 from a bond trader who did business with the state was a felony rather than just a lapse in ethical judgment.

Shoffner wept quietly at the defense table before the jurors, who deliberated for about three hours, returned to the courtroom. But the former Democratic official regained her composure and showed no reaction as U.S. District Judge J. Leon Holmes read the 14 consecutive guilty verdicts.
