Cooper later wrote a letter to Philip Schuyler, Alexander Hamilton"s father-in-law, in which he made reference to the "despicable opinion" Hamilton had expressed about Burr.
The letter was published in the Albany Register, but was tame compared to other attacks on Burr in the press Still, Cooper"s letter proved the last straw in the ongoing rivalry between Burr and Hamilton.
