The former national security advisor objected to Trump's actions with Ukraine.
Topline: As the impeachment probe around Trump's pressuring of Ukraine to investigate the Bidens continues to intensify, the next star witness who could deliver public testimony is former national security advisor John Bolton, who has been described in previous testimony as alarmed and disturbed by the president's actions.
What to watch for: House Democrats moved quickly to investigate Trump's actions with regard to Ukraine after the whistleblower complaint emerged. While there have already been several closed-door sessions, the next steps will likely include high-profile hearings that could begin as early as November, in which Bolton could play a crucial role.
Tangent: Trump fired Bolton as national security advisor last month, saying he " disagreed strongly with many of his suggestions," while Bolton insisted that he had first " offered to resign."
