[vmh1928]

A constitutional republic is where the people delegate certain powers, enumerated in a constitution, to the government. The Constitution of the United States defines three branches of government, the Legislative, Judicial and Executive. Ideally each branch serves to check the unrestrained power of the other branches (or two branches check the unrestrained power of the third.) That's what makes the revelations about mass logging of emails by the NSA, part of the Executive branch, so important.
