Former Clinton campaign manager Robby Mook dropped a bombshell in court on Friday - testifying that Hillary Clinton approved the dissemination of allegations that then-candidate Donald Trump had a covert communications channel with a Russian bank, despite campaign officials not being "totally confident" in the rumor, according to Fox News.

Mook, who was called to the stand by the defense team for former Clinton lawyer Michael Sussmann, was asked under cross-examination about the campaign's understanding of the allegations against Trump, and whether the campaign planned to release it to the media.
