WATCH: Tucker Presses Vegas Guard's Union Rep on Canceled Interviews, Mexico Trip
Tucker Carlson asked Las Vegas security guard Jesus Campos' union representative several unanswered questions about the officer and the events of the past few weeks.
David Hickey, the president of the Security Police and Fire Professionals of America, said Campos was not licensed by the state of Nevada - a question Tucker asked aloud on Wednesday.
Hickey said that employees working for contractors must register, not 'in-house' security.
Carlson asked whether Hickey knew Campos traveled to Mexico after the shooting.
Hickey said he knew, and that Campos had pre-planned the trip - and was able to travel despite being wounded by bullet fragments in his thigh from shooter Stephen Paddock.
He added that investigators didn't have a problem with the trip because it was scheduled and he returned in a timely fashion.
Carlson asked why he cancelled several interviews, including with FNC's Sean Hannity.
Hickey said that only Campos can speak for that, as he is allowed to make personal decisions about speaking with the press.
He said Campos is still employed by Metro-Goldwyn-Mayer, the parent company of Mandalay Bay.
