My first dive into google says Thomas was involved originally with Danforth in this respect:
Born in tiny Pinpoint, Georgia, a small community near Savannah, Justice Thomas grew up in a Georgia that was segregated for most of his childhood years. Still, he excelled in his studies, attending Holy Cross College and Yale Law School. He accepted a position in Jefferson City, Missouri, where he practiced tax law as an Assistant Attorney General to John Danforth, then Attorney General of Missouri.
Danforth was impressed by the ability of Thomas, but Thomas left the state and took a position with the Monsanto Corporation, where he supervised much of the regulatory agency interaction for the large St. Louis-based company. In 1979 Danforth, who had been elected Senator, asked Thomas to join him in Washington D. C. During this time that Thomas got a broad range of experience, starting as Danforth's legislative assistance. His meteoric rise began in the Department of Education, moving to head the Equal Employment Opportunity Commission in less than a year.

I'll look around for more info.
He has had a very decent rep in every other way.
Bush isn't fit to shake his hand.
On edit:
However, in his defense, I'll bet it's hard for a man who was acquainted with the guy, as his elder, and his sponsor over a number of years, and was accustomed to being treated with respect and deference, as his senior and his employer, seeing nothing but the best from the guy, imagine seeing him ALSO as a man who could strut around and act like a total jackass to people he thought had absolutely no authority!
Common mistakes many people make, in assuming one "knows" another from a formal relationship, and also, as in Thomas's case, assuming people with less power really just have to grin and bear it.
Thomas, as his employee, and a person hoping to work up the chain, politically, UNDOUBTEDLY showed him only his best face.
