Run a secret pen register on the entire U.S. population, collecting records of what number called what number when? No problem.
Monitor phone calls of millions of ordinary people in France, Germany, Spain? No problem.
Intercept and listen to phone calls by anyone in the U.S. who there is any basis, however flimsy, for maybe possibly connecting to international terrorism? No problem.
Do all of this under secret interpretations of the relevant law by government lawyers? No problem.
Listen in on the phone calls of important people, people like her? That is an entirely different matter that clearly calls for a Senate investigation.
