UPDATE: The quote attributed to Ivanka Trump by The Chicago Tribune did not originate with her, reports Snopes' Dan Evon. Fake.
Kendizor evidently found Ivanka's alleged "mace" quote in the "Quotables" section of the Chicago Tribune. The screen shot she shared was real, and was published by the newspaper in August 2006:
"If he wasn't my father, I would spray him with Mace." … The same quote, along with the same attribution, also appeared in an end-of-the-year quiz by the Telegraph. However … The earliest version of this quote we could uncover was published on 17 March 2006, in the "News For Dumb Guys" section — a weekly feature in Louisiana's Shreveport Times — where it was attributed to comedian Conan O'Brien
In 2006, president-elect Donald Trump remarked that if Ivanka Trump wasn't his daughter, "perhaps I'd be dating her."
In response, she said "If he wasn't my father, I would spray him with Mace." (CORRECTION: The Ivanka Trump quote from The Chicago Tribune is fake, reports Snopes. Sorry Ivanka.)
The remark was unearthed by Sarah Kenzidor from the Aug. 24, 2006 issue of The Chicago Tribune; it's one of several.

"Yeah, she's really something, and what a beauty, that one. If I weren't happily married and, ya know, her father . . . " Trump said to Rolling Stone in 2015.
In a 1999 interview with radio host Howard Stern, Trump said his daughter ― who was then 17 ― made him promise he would never date a woman younger than her.
Reminder: the incoming President of the United States of America wants to bang his daughter.
