A common occurrence at Donald Trump’s campaign events is when the candidate introduces his daughter Ivanka along with her husband Jared Kushner to the crowd. Often he’ll ask Ivanka to say a few words about her father will “make America great again” or Trump will note that Kushner is “a successful real estate entrepreneur from New York but that he may be enjoying campaigning more.”

On Friday, after coming under attack from his rivals Marco Rubio and Ted Cruz at the CNN presidential debate on Thursday, Trump rolled out a surprised endorsement by his former rival and New Jersey Governor, Chris Christie. “Donald is a leader. He is a successful person that, like me, isn’t afraid to tell it like it is,” Christie said during a press conference in Texas. “Our system is broken and it won’t be fixed from the inside. I am proud to offer my endorsement of his candidacy for President.”

Twitter was quick to highlight the warm ties between Trump’s son-in-law and the outspoken New Jersey Governor, now one of his attack dogs in the race for president.

“Trump’s son-in-law Jared Kushner to receive $93M in tax breaks from Chris Christie’s State government,” read a tweet by Jewish Insider in November 2015. The tweet linked to a report by The Jersey Journal: “One Journal Square, the 666-foot, 56-story tower proposed by Kushner Companies and KABR Group, could receive $34 million in tax credit from the state Economic Development Authority at the agency’s Nov. 13 meeting. The EDA is also considering a separate round of tax credits totaling $5.9 million annually over 10 years for an entity connected to trendy office space provider WeWork that may be housed in the new tower. Kushner Companies, headed by Jared Kushner, and KABR announced in January that they purchased the lot for $27 million.”

Christie’s relationship with Kushner dates to his time as New Jersey’s U.S. attorney under President George W. Bush. Back then, the International Business Times reported, Christie prosecuted his father Charles Kushner, using documents pried from the Kushner siblings’ bitter, sealed legal feud for control of their family’s real estate company.

For whatever it’s worth, David Wildstein, who Christie fired over the bridgegate scandal worked for PolitickerNJ which Jared Kushner owns.
