Catherine Herridge reported that Fox News had obtained the draft letter of former FBI Director James Comey's "exoneration statement" of Hillary Clinton, and that there's more evidence that the FBI let her off the hook.

Here's the report from Fox News:

According to Herridge, the letter shows two ways in which the FBI later edited the statement to ease the accusations against Clinton in the heat of the election campaign.

Was Clinton's private server hacked?

One edit lowers the certainty that the FBI has that the private server Clinton set up had been hacked.

In an early draft, Comey said it was “reasonably likely” that “hostile actors” gained access to then-Secretary of State Hillary Clinton’s private email account. That was changed later to say the scenario was merely “possible.”

'Careless' or 'negligent'?

A second edit lowered the severity of the specific transgression Clinton was being investigated over.

Another edit showed language was changed to describe the actions of Clinton and her colleagues as “extremely careless” as opposed to “grossly negligent.” This is a key legal distinction.

This edit had been previously reported as being that made through the efforts of FBI official Peter Strzok, who was later demoted from special counsel Robert Mueller's investigation into Russian meddling over anti-Trump texts.

Why is this important?

Allies of President Donald Trump have been building a case that the FBI and the Department of Justice are biased against Trump and that the investigations into Russian election interference and alleged collusion with the Trump campaign have been irreparably tainted. This report, if accurate, provides some support for that supposition.
