So now a whistleblower with credibility saying that Hillary Clinton's State Department covered up misbehavior by an American Ambassador and other State Department officials; prostitution and drugs are allegedly involved.

JEN PSAKI, STATE DEPARTMENT SPOKESPERSON: I'm not going to talk about specific cases. But I can say broadly that the notion that we would not vigorously pursue criminal misconduct in a case, in any case is preposterous.

O'REILLY: Ok, fine another round of investigations loom. We now add this sordid situation in Benghazi, the IRS, spying on reporters, and the possible spying on calls and e-mails made by American citizens. What's next? Breaking into a Washington hotel?

It's clear the Obama administration is under siege with all these allegations. And the President himself must step up and stop the chaos.

Surely he knows what happened in Libya by now. So he should tell us who ordered Ambassador Rice to mislead the world? Who denied protection to the Ambassador when he asked for it? And who gave the stand down order on September 11th?

Also, the President should have asked Attorney General Holder to resign last week. The top law enforcement officer in the country cannot sign off on a document calling a reporter like James Rosen a co-conspirator to a crime and a flight risk and still keep his job. Come on.

In addition, the President must explain in full the PRISM program. Is the federal government collecting the e-mails of Americans and storing them? Yes or no, Mr. President?

Finally, the President must order any IRS official involved in targeting conservatives to testify fully in front of Congress or resign. It is Barack Obama's obligation to run this country honestly. And to explain to the folks complicated matters and serious allegations. Just saying he'll get to the bottom of things is not nearly enough. We need presidential leadership on these serious situations now.

If Mr. Obama does not clarify all of the controversies he'll go down in history as U.S. Grant, a scandal-ridden President who lost control of the office. There is no longer any doubt the federal government is deeply involved in situations that are harming the American people. And this must stop immediately.

The President and Congress cannot concentrate on serious issues like immigration reform, soft economy, Iran and the institution of national healthcare mandates with one scandal after another diverting everybody's attention. Time to stop the madness, Mr. President.

And that's "The Memo."
