From Theodore Rex by Edmund Morris:
Roosevelt came to the defense of a beleaguered black postmaster in Indianola, Mississippi, who also happened to be female.
He knew her territory: Indianola stood not far from where he had hunted bear last fall. Appointed by President Harrison and reappointed by McKinley, Mrs. Minnie Cox was by all accounts a worthy citizen. She administered her office efficiently and even charitably, paying overdue box feeds herself rather than embarrass white customers short of funds. But she had also invested her federal salary in local businesses, and become prosperous over the years. By local definition, she had therefore become uppity. At a mass meeting, white Indianolans chose to “persuade” her to resign.
…she had needed little persuasion. After hurriedly resigning, she had left town on vacation–the mayor of Indianola allowing that if she came back too soon “she would get her neck broken inside of two hours.”
Roosevelt’s reaction was prompt and precisely articulated. Mrs. Cox was being coerced “by a brutal and lawless element purely upon the ground of color.” He declined to “tolerate wrong and outrage of such flagrant character.” Neither would he stop paying Mrs. Cox her full federal salary. “The postmaster’s resignation has been received, but not accepted.”
In deference to the feelings of white Indianolans, however, he would not reopen her post office. In future, they could pick up their mail at Greenville, thirty miles away by country road.
