A FOR EFFORT? Susan Rice somehow manages to make Benghazi cover-up seem minor.

What is so astonishing about the revelation that Ms. Rice was the one unmasking Donald Trump and his campaign before, during and after he won the presidency is that it doesn’t get any closer to Barack Obama himself.

Ms. Rice was Mr. Obama’s national security adviser, one of his closest aides. They spoke all the time. She worked directly for him. Here she was spying on Mr. Obama’s political enemies while in daily contact with him at the very height of the most contentious presidential election in memory. You don’t think she and the president discussed this?

The revelation that Ms. Rice was the operator behind the spying answers just one question. But it raises a thousand more.

When, exactly, did Ms. Rice start using the U.S. government’s spy operation as a weapon against Mr. Obama’s political opponents?

What conversations did she have with the president about the intel gleaned about Mr. Trump and other political enemies of Mr. Obama?

As was asked of an earlier president amid far smaller crimes: What did the president know, and when did he know it?

Indeed.
