Now, Mr Robinson has been revealed to have been in a "romantic relationship" with his trans partner, who is a male transitioning to a female.

The partner, who remains unidentified, is fully cooperating with the FBI in its investigation into Mr Kirk's killing - which Donald Trump has labelled a "heinous assassination".

Fox News revealed last night that the couple shared an apartment in Saint George, Utah.

Then, the pair's neighbour Josh Kemp, 18, confirmed the report - adding: "I saw them holding hands. They drove off in Tyler's car. It was about two weeks ago.

"They looked like they were a couple and he was dressed all in black.
