Trump once told his biracial ex-girlfriend that her intelligence came 'from her dad, the white side,' book claims

• Trump told his biracial ex-girlfriend that she gets her intelligence from her "white side."
• The comments were made to model Kara Young after meeting her parents, according to a new book.
• The former president laughed at his comments while Young rebuffed the remark. 

Former President Donald Trump once told his girlfriend, who is biracial, that she gets her intelligence from her white father, according to a book.

The new book "Confidence Man The Making of Donald Trump and the Breaking of America" by New York Times reporter Maggie Haberman detailed Trump's past relationship with model Kara Young, Rolling Stone reported.

Young and Trump dated in the late 1990s and frequented movie premieres and other social events in New York City. 

After Trump met Young's mother, who is Black, and father, he made a joke insinuating that her looks come from her mother, but her intellect comes "from her dad, the white side," the outlet reported, citing the book. 

Per the book, Trump laughed at his joke, but Young did not appreciate his comments, according to the report. 

Trump has continuously come under fire for remarks on race during his presidency, from publicly slamming the Black Lives Matter movement, touting a birther conspiracy against former President Barack Obama, and his comments after the Charlottesville protests. 

Young opened up about another experience in 2017 where she said Trump was shocked that Tennis juggernauts Serena and Venus Williams were able to attract a diverse crowd to the US Open, Rolling Stone reported. 

The book also recounts another incident during a reception at the White House when Trump mistook a racially diverse group of congressional aides as waiters in 2017. 

"Why don't you get" the food," Trump asked the group, who was part of Sen. Chuck Schumer and Rep. Nancy Pelosi's staff. Ex-White House Chief of Staff Reince Priebus corrected Trump's remarks and got the actual waitstaff.
