Lawmakers say administration’s lack of candor on surveillance weakens oversight

The Washington Post reports:

Lawmakers tasked with overseeing national security policy say a pattern of misleading testimony by senior Obama administration officials has weakened Congress’s ability to rein in government surveillance. Members of Congress say officials have either denied the existence of a broad program that collects data on millions of Americans or, more commonly, made statements that left some lawmakers with the impression that the government was conducting only narrow, targeted surveillance operations.
