The presidential aspirant has caused outrage for his menacing comments against migrant communities, who he blames for the acts of terror against the United States.
According to Us Magazine, Sandford tried unsuccessfully to grab the gun of a police officer in a bid to assassinate Trump.
The suspect revealed that he has been training himself on how to use a gun so he can kill the politician.
He reportedly visited Battlefield Vegas, one of the shooting range in the state on Friday, June 17, 2016, to prepare himself for the mission.
This was confirmed by detectives investigating the case, who visited the range to determine the truth in the suspect's claim.
Donald Trump has made a fight against the American Muslim community the subject of his campaign. He blamed migrant communities for the acts of terror faced in the United States.
This has however seen widespread criticism from other politicians and the current president of the US, Barack Obama.
