ATLANTA -- The father-in-law of the tuberculosis patient under the first federal quarantine since 1963 works in a CDC laboratory aimed at preventing the disease and has co-authored papers on tuberculosis.

Bob Cooksey said he gave his son-in-law Andrew Speaker "fatherly advice" when he learned he had contracted the disease. Speaker has a rare and dangerous form of tuberculosis that has proved resistant to drugs.

Cooksey said that had he knew his daughter was at any risk, he would not have allowed her to travel. He said he did not act in any official capacity with the CDC on the case.

Cooksey, a microbiologist at the CDC's Mycobacteriology Laboratory Branch, said his daughter Sarah married Speaker a few weeks ago.

A spokesman for the Colorado hospital where Speaker will be treated said doctors plan to begin immediately with two antibiotics, one oral and one intravenous. He also will undergo a basic physical exam, a test to evaluate how infectious he is and a C-T scan and lung X-ray.

Speaker is a 31-year-old personal injury and divorce attorney who practices law with his father in Atlanta. According to a biography posted on a Web site connected with Speaker's law firm, he attended the U.S. Naval Academy, graduated from the University of Georgia with a degree in finance, then attended University of Georgia's law school.

His father, Ted Speaker, unsuccessfully ran for a Fulton County Superior Court judgeship in 2004, the same year his son was admitted into the Georgia Bar.
