Ex-FBI agent: Americans should be 'disgusted' by Russian interference in Mueller report

Americans should be "disgusted" by the amount of Russian interference in the U.S. electoral system that is laid out in special counsel Robert MuellerRobert (Bob) Swan MuellerFox's Cavuto roasts Trump over criticism of network Mueller report fades from political conversation Trump calls for probe of Obama book deal MORE's report, a former top FBI official told Hill.TV on Friday.

"The attorney general said that Americans should celebrate that there were no Americans involved in collusion with the Russians. My take was Americans should be disgusted, frankly," Kevin Brock, former FBI assistant director of intelligence, told hosts Krystal Ball and Buck Sexton on "Rising."

"Where they're celebrating is in Moscow and the Kremlin," Brock said. "The origin of this was clearly a Russian active-measures campaign, which is a fancy way of saying a propaganda initiative on the part of Russian intelligence, to sow discord into the U.S. election," he said. "They had some success at that."

"I think the attorney general is correct on this: We have to go back to the beginning and look and see how did this start. How did we get to this point where we're embarking on, literally, a convulsion of our political system to try to chase something down that proved to be a falsehood?" Brock added.

Attorney General William Barr on Thursday released a redacted version of Mueller's long-anticipated report.

The special counsel's office detailed Russian efforts to try to help Trump win the 2016 election, but noted that the Trump campaign did not directly assist Moscow in that effort.

Mueller described how a Russian troll farm connected to the Kremlin worked to create divisions among the American public on social media.

The report also detailed how Russian intelligence officers hacked both the Democratic National Committee and Democratic nominee Hillary Clinton's campaign chairman John Podesta.
