> Again, they didn't state that he lied. They stated that he wasn't candid. A lot of people here have been reading specifics into a generalized term.
OED:
candour - the quality of being open and honest in expression.
"They didn't state he lied ... without even using lies of omission ... they said he wasn't [word defined as honest and open]"
Candour encapsulates exactly those things. Being open (i.e. not omitting things and disclosing all you know) and honest (being truthful).
On the contrary, "not consistently candid", while you call it a "generalized term", is actually a quite specific term that was expressly chosen, and says, "we have had multiple instances where he has not been open with us, or not been honest with us, or both".
