The one-minute, 16-second clip, which does not capture any sound, shows Hansen briskly walk toward the mayor and a prolonged chest-to-chest argument as a half dozen people along with two reporters watch from the middle of the hallway.
In the final seconds, the video shows Anderson yank his arm away from Hansen who crowds the mayor while both men make their way slowly down the hall.
The video does not show the final seconds of the confrontation where Anderson and Hansen had to be separated by three people in front of an elevator. There is no camera on that side of the hallway, the mayor's spokesman explained.
In a statement released with the recording, Anderson says the security camera "gives a true picture of events."
"Mr. Hansen's aggressive and threatening conduct, and his loud, abusive harangue, were witnessed by several people, including two newspaper reporters who were only a few feet away," the statement reads.
Reporters trailing the hallway "harangue" heard Anderson say "I will kick your ass," but that came after Hansen stalked then grabbed the mayor by the arm. Anderson also did not repeatedly yell "I'm going to sue you," but said "sue me" mockingly.
The mayor also released partial transcripts of interviews Hansen gave KSL radio and KUTV on Wednesday - with comments Anderson takes issue with put in bold. They include: "As we walked out, Rocky moved to my shoulder and I turned to him and said, 'Rocky, why didn't you call me?' . . . He was in the aggressive, I simply asked, 'Rocky, you could have called me. We don't need to go through the political theater.'"
Hansen also told KSL the mayor was "a foot and a half away," and that Anderson "raised his finger and said 'I'm going to kick your ass. I'm going to kick your ass.'"
"And I reach up and put my arm forward and touched his forearm, he said, 'I'm going to sue you. I'm going to sue you,' " the transcript continues.
Anderson did not comment directly Thursday. But his spokesman said the mayor released the video "because of Dell Loy Hansen's complete misrepresentation of the facts."
"Those things speak for themselves."
Attempts to reach Hansen, CEO of Wasatch Property Management, were unsuccessful.
"At this point in time, he doesn't want to talk about it," a secretary for Wasatch said late Thursday.
The dispute stems from a June 1 letter the mayor sent to the city's redevelopment agency that calls on the RDA to reconsider $1 million for a planned 21-story office tower at 222 S. Main St., which Hansen was helping finance. Minutes before the hallway encounter, Hansen announced to the RDA board he was pulling his funding from the project, blaming Anderson in the process.
Anderson argues Hansen abused a previous RDA loan, refinancing without disclosure and improperly claiming interest credits for new employees. The dispute could end up in court.
A groundbreaking on the high-rise has been delayed until August while Hansen's former partner, Hamilton Partners, searches for a new investor.
Bruce Bingham, of Hamilton Partners, confirmed that Hansen decided to abandon the project prior to the mayor's June 1 letter.
