Federalist No. 75, authored by Alexander Hamilton under the pen name Publius, is the seventy fifth of 85 essays. Titled "The Treaty Making Power of the Executive", Hamilton explains that the President is only to have power to make treaties "by and with the advice and consent of the senate to make treaties provided two-thirds of the senators present concur."
It was published on March 26, 1788.
Hamilton notes the importance of presidential cooperation with the representatives of the states, the senators, in making treaties. One man alone cannot and should not do this.
