From this:

Phoenix Mayor Phil Gordon, a renowned open borders advocate who claims detaining illegal immigrants violates their civil rights, was under investigation for giving his girlfriend more than $340,000 to help him get reelected and raise funds for various city initiatives. More than half of the money - at least $200,000 - was paid while the 58-year-old mayor was romantically involved with the 38-year-old consultant.

Arizona law forbids these sorts of shady arrangements in which politicians’ family members, or the politicians themselves, benefit from such campaign largess. Girlfriends are not covered by the statute, however. Because the consultant/fundraiser (Elissa Mullany) only sleeps with the mayor and is not related to him, he’s off the hook.
