John Bolton got a book deal after he was fired by Trump, so any appearances in favor of Democrats will be another in a lifetime of expedient acts. We can’t forget his history of what some would call war crimes, but so many such criminals continue to walk free in the US. His value to the House committees inquiring about impeachment remains important to fill in what will be a now solid case to impeach PABOTUS*.

There is a wrinkle that could affect the role of WH witnesses: his deputy, Charles Kupperman, and NSC’s current Russia and Europe director, Tim Morrison, can substantiate Bolton’s allegations of  the Trump shakedown. But Kupperman is filing suit to test whether they can be called by Congress.

Lawyers for former national security adviser John Bolton have had talks with the three House committees leading the impeachment inquiry about a possible deposition, according to a source familiar.

If he does give a deposition, Bolton would join a handful of current and former Trump administration members who have been interviewed this month as part of the Democratic-led inquiry into President Donald Trump’s dealings with Ukraine.
As House members who serve on the Intelligence, Oversight and Foreign Affairs committees have been interviewing witnesses in private, some of the committees’ Democrats have said they believe there’s a need for Bolton to testify.
Fiona Hill, Trump’s former top Russia adviser, told lawmakers last week that she saw “wrongdoing” in American foreign policy and that Bolton had encouraged her to report her concerns to the National Security Council’s attorney, sources had told CNN.
    A source told CNN that Hill testified that Bolton referred to Trump’s personal attorney Rudy Giuliani, who was working to dig up dirt on the Bidens, as a “hand grenade,” who was “going to blow everybody up.”
