Donald Trump Jr. joins 'America's Newsroom' after attending the preliminary hearing for accused Charlie Kirk assassin Tyler Robinson.

Donald Trump Jr. said Tuesday that evidence presented during the preliminary hearing for the man accused of assassinating Turning Point USA co-founder Charlie Kirk was "much more cut and dry" than he expected, saying newly released surveillance video and witness testimony left little doubt in his mind about the prosecution's case.

"Once this hard evidence was laid out to me in a courtroom before my very eyes, [and] seeing the reaction of the defense, this thing is much more cut and dry than I would have ever even imagined," Trump Jr. told "America's Newsroom."

The president's eldest son expressed confidence that suspect Tyler Robinson will be found guilty once the case has concluded, saying the outcome is "very clear."

Robinson's preliminary hearing began Monday and is expected to take all week. 

Prosecutors must establish probable cause in order for the judge to green-light the path to trial on a slew of charges, including aggravated murder, which carries the potential death penalty.

Robinson is accused of fatally shooting the 31-year-old Kirk during a Turning Point USA event at Utah Valley University on Sept. 10 last year.

Trump Jr. attended the hearing to show support for Kirk's legacy as well as Kirk's widow, Erika, and his parents.

He told Fox News he wanted to see the evidence firsthand after declining to publicly weigh in on speculation surrounding the case.

"It was just important to be there. It's a legacy that really needs to be preserved," he said.

"The impact that Charlie had on so many Americans, on so many youth, is, frankly, generational. It could have been so much more, but it was important to be there and to see the actual facts laid out."
