Answer:
Signing statements go beyond the president’s expressed constitutional powers
Step-by-step explanation:
A signing statement is a written pronouncement issued by the President of the United States upon the signing of a bill into law.
Presidents use signing statements to explain to the public why they endorse a bill and what the President understands to be its likely effect. However, the President can not cherry-pick the parts of a duly enacted law that the President will choose to follow, or an attempt unilaterally to redefine what the law is after its enactment. Therefore, Fish's argument is valid that signing statements go beyond the president’s expressed constitutional powers.
