substantiates
Backs up claims
Substantiates means provides evidence or proof for a claim.
To substantiate an accusation is to back it up with facts: The reporter couldn't substantiate the allegations.
The word implies moving from assertion to demonstration—showing that something is true rather than merely claiming it.
DNA evidence substantiated his alibi.
