St. Clair County Circuit Judge Robert LeChien kept an online account for betting on horse races around the world as of May 18, according to his statement of economic interest at the Illinois Supreme Court.
Among his interests he listed an open account with Twinspires, a subsidiary of Churchill Downs in Louisville, Ky.
Twinspires and other sites carry out wagers by drawing funds from accounts their clients can replenish as necessary.
They call the method advance deposit wagering.
The busiest sites offer races around the world and around the clock.
LeChien resigned as judge last year, in order to run for partisan election this year rather than stand for non partisan retention at 60 percent.
On Sept. 6, class action lawyer Stephen Tillery of St. Louis contributed $2,500 to LeChien’s campaign.
