Resolves YES the first executive order of Trump's second term is primarily about immigration and/or border security, NO if it is not primarily about either topic, and N/A if he has not signed any executive orders by April 29th (i.e. first 100 days).
Context
The first executive order of Trump's first term was #13765, a.k.a. "Executive Order Minimizing the Economic Burden of the Patient Protection and Affordable Care Act Pending Repeal". An equivalent market would have resolved NO.
From his first term, the first executive order that would have resolved an equivalent market YES was his 3rd, #13767, "Border Security and Immigration Enforcement Improvements".
For more examples, his 4th & 5th executive orders in 2016 would also have resolved this YES.
Regardless, there will naturally be some subjectivity in resolution. I intend to be fairly broad, but it needs to be primarily about immigration and/or border security, not just indirectly influence on these topics.
