Which is an example of the president interpreting the details of a law? a. changing travel laws based on the homeland security act b. signing a spending bill passed by both houses of congress c. asking congress to pass tax legislation d. asking congress for a declaration of war

The correct answer is option A:

President Donald Trump signed an executive order immediately after coming into office banning entry to the United States of America to citizens of several countries with large Muslim populations. The measure caused an international uproar and severe gridlocks at international airports.

Several lower courts struck down most of its provisions soon there after but the Supreme Court later upheld it.
