Federalist No. 64
Federalist No. 64, the last of five papers authored by John Jay under the pen name Publius, is the sixty fourth of 85 essays. Titled "The Powers of the Senate", Jay elaborates on what the powers of the senate are and why those powers rest with this branch.
It was published on March 5, 1788.
Federalist 64 is only one of a few Federalist papers to have a known original draft still in existence. When it was revealed that the original draft was in John Jay's handwriting, that resolved a previously long-standing controversy over the paper's authorship.
