CBS News contributor and cybersecurity expert Chris Krebs and intelligence and national security reporter Olivia Gazis joined “Face the Nation with Margaret Brennan” to discuss the alleged hack of the Trump campaign, as some outlets reported receiving what appeared to be sensitive internal campaign documents. The campaign blamed Iran and urged reporters not to publish anything they received as a result of the hack. Krebs said the apparent hack appears to be a “replay of the 2016 Russia scenario,” when the Democratic National Committee was infiltrated by Russian actors.
