State Sen. Tommy Brooks resigned from the Mississippi Legislature more than two decades after he first entered it and two days after his conviction in Jackson on a federal charge of attempted extortion. Gov. Bill Allain will call a special election to fill the vacancy. Brooks, 60, was convicted of attempted extortion for trying to exchange his Senate influence for $52,000 in cash and $19,000 in stock from a group trying to legalize horse racing. He is to be sentenced July 18 and faces a maximum penalty of 20 years in jail and a fine of $10,000.
