The 1968 act specified that it did not mean to circumscribe the president's authority to protect the nation against foreign threats, nor did it prevent him from securing vital foreign intelligence information, nor deter him—and this is the critical language—from "protect[ing] national security information against foreign intelligence activities." This vague wording could be construed to mean one of two things—either that the president did not, in fact, need a warrant to engage in wiretapping where foreign threats were involved or, alternately, that Congress simply wasn't legislating on the question of national security wiretapping at all.
