Who is Congressman William Stanbery from Sam Houston and the American Southwest and what is their importance?

Stanbery wrote a newspaper article questioning the ethics of Sam Houston in regards to a deal involving Indian rations. Enraged, Sam Houston beat the man with a cane in the middle of a street. Houston was arrested and forced to defend himself in a trial on the congressional floor. This incident, though it ended in Houston's official admonishment, put Houston back on the road to political prominence.
