State Rep. Steve Cookson is scheduled to begin undergoing tests May 1 in preparation for a life-saving liver transplant. The 58 year old visited Doniphan last week, three days after making national news by announcing his illness for the first time during discussion of a bill on the house floor in Jefferson City. The proposed bill removes the expiration date for a tax-checkoff program for the Missouri Organ Donor Trust Fund. The House gave overwhelming support to the bill. Cookson has been diagnosed with liver failure and needs a transplant to survive. He says this is a result of blood viruses transmitted through a blood transfusion in the 1970s. He said he hopes to receive a transplant after the legislative session ends May 12. He plans to finish the rest of his term if he can maintain his health. He is serving his fourth and final two-year term due to term limits.
