But the video, titled "Trump and the extreme right-wing" on the Clinton campaign's The Briefing channel on YouTube (and also released on Twitter and Facebook), was only part of a relentless social media attack on Trump for the way his campaign has subtly and not-so-subtly courted racist voters and organizations. The barrage -- which also included slide shows of disturbing Breitbart News headlines and longform posts on Medium and HillaryClinton.com -- was designed to set the stage for Clinton's so-called "alt-right" speech on Thursday in Reno, Nevada (CNN: "Clinton: Trump campaign built on 'prejudice and paranoia'").

The barrage comes in a wake of Donald Trump's campaign-trail declaration that "Hillary Clinton is a bigot."
Trump has tentatively started to respond to Clinton's return fire on Twitter:
Just watched recap of #CrookedHillary's speech. Very short and lies. She is the only one fear-mongering!
