Even Sen. Lindsey Graham (R-S.C.) wants to hear from John Bolton.
After a report indicated former National Security Adviser John Bolton's forthcoming book would describe President Trump calling for a Ukraine quid pro quo, Sen. James Lankford (R-Okla.) said Monday that senators "should get access to that manuscript to see what they're actually saying." Graham agreed with Lankford's proposal in a Tuesday tweet, but added he would like the manuscript to be viewed "if possible, in a classified setting."
I totally support @SenatorLankford's
proposal that the Bolton manuscript be made available to the Senate, if possible, in a classified setting where each Senator has the opportunity to review the manuscript and make their own determination. https://t.co/e18nUfSMgI

Bolton's manuscript had gone to the National Security Council for review before its publication, and according to a Sunday New York Times report, it describes how Trump told Bolton he wanted to withhold Ukraine's security aid until the country agreed to investigate his Democratic rivals. Lankford said Monday that "we may" need "witnesses and additional testimony and additional evidence" if "questions are not answered" by the manuscript, though he did say "there’s plenty of microphones all over the country" Bolton should use to speak out now. It's unclear if Graham agreed with that part of the statement.
