Letter to King March 5th
King's Response March 10th
Response to King March 15th by a constituent. It is admittedly not very polite. It refutes what King said in his letter to a constituent.
King's Response #1 - Incomplete. Why? Who knows. It was sent this way.
King's Response #2 - Okay, so maybe that's all he wanted to write.
Response to King - Which was never acknowledged. Oh well.
