This is pretty much the John Bolton who was despised by his staff at the United Nations:

Bolton has clashed w/most departments in White House repeatedly. Example: An acerbic hallway fight w/Staff Sec Derek Lyons because he wouldn’t immediately release a Bolton statement. “Did you have fun today?” he taunted Lyons. “You better watch out buddy.” https://t.co/G3MsKVMwKC
