Clinton said "everyone understands" he and Hillary Clinton won't be involved in the race "as long as our personal friends and people we feel obligations [to] are involved," CNN reported.
Interviewed in Kigali, Rwanda, during a six-day tour of Africa, the ex-president said "there are too many people running for mayor who have been my supporters, who supported her [Hillary Clinton] for senator, for president."
He added there were "literally five people" in the race, including a Republican candidate, who were "personal friends."
"Since they are, I shouldn't talk about them," Clinton added.
