Controversy
concerns were raised over Hughes' business relationship with developer Kevin Garn while Hughes was serving as the Utah Transit Authority board chairman. In April 2011, Greg Hughes and former House Majority Leader Kevin Garn formed a company together to construct an apartment building on land that Hughes owned in downtown Salt Lake City. Several months later, UTA chose a separate company owned by Garn to develop several transit-oriented developments. Hughes was the UTA board chairman at that time, and did not disclose a business relationship with Garn. In 2018, The Salt Lake Tribune reported on a conflict-of-interest controversy as part of on ongoing federal probe into the Utah Transit Authority. Questions were raised in 2016 surrounding the company "Urban Chase Property Management", which is co-owned by Hughes, that would use surplus property owned by UTA. Newly-released documents from 2016 show that UTA believed that "Greg Hughes' proposed participation in this project, even if it is just as an investor, appears to be a conflict of interest." Hughes had no comment due to an ongoing federal investigation, but documents indicate Hughes "did not know the project was related to UTA." In June of 2018, a conflict-of-interest caused Greg Hughes to step down from his self-appointed position on the board of the Utah Inland Port Authority after it was discovered that he was registered with at least eight companies owning land within five miles of the inland port. Hughes said he had been unaware that his land was within the disqualification boundary.
