We could have done more.

So writes Andrew Weissman in his new book Where Law Ends, the first insider account of

Robert Mueller's investigation into Russian interference in the 2016 election and its

links to the Trump campaign.

Weissman was one of Mueller's top deputies, heading up the investigation and prosecution

of former campaign chairman Paul Manafort.

But Weissman argues that the Mueller probe didn't go far enough, especially when it came

to investigating President Trump's own culpability.

But what exactly does he think the special counsel should have done?

And how much did Weissman himself speak up about all this at the time?

As President Trump remains fixated on the Russia probe, demanding that his investigators

themselves be charged with crimes, we'll talk to Weissman about where he thinks the

Mueller probe pulled its punches.

And what it could have done differently on this episode of Skull Duggery.

Because people have got to know whether or not they're President of the crop, well,

I'm not a crop.

I told the American people I did not trade arms for hostage.

My heart and my best intentions still tell me that's true, but the facts and the evidence

tell me it is not.

I did not have sexual relations for that woman.

There will be no lies.

We will honor the American people with the truth and nothing else.
