Former Trump Chief of Staff John Kelly recently stated that he believes whatever Bolton puts in his book in regards to his time in the Trump administration and also supports witness testimony in the Senate trial.

According to the Florida Herald Tribune:

Asked if Bolton – Trump’s former national security adviser – should testify at Trump’s impeachment trial, Kelly said he supports calling witnesses.

President Donald Trump is denying that he told former National Security Advisor John Bolton he wanted to withhold military aid from Ukraine until the country launched investigations into Joe Biden and his son, allegations that Bolton levies in his new book, according to news reports.

But one of Trump’s former top aides told a Sarasota audience Monday evening that if the reporting on what Bolton wrote is accurate, he believes Bolton.

“If John Bolton says that in the book, I believe John Bolton,” said retired Gen. John Kelly, who served as Trump’s chief of staff for 18 months.

Kelly stated that he always witnessed John Bolton give the “unvarnished” truth to President Trump during his time in the White House.
