Constitutional right to face your accusers.Actually Trump got ALL of the January 6th committee transcripts, every darn one of them, which was pointed out to Trump's lawyers, who made false claims in court, that they didnt.
Once corrected in court on that they changed their tune and said they wanted certain video evidence from January 6th with no reason as to why it was important to his case. Trump team is behind on letting the judge know what parts of the discovery evidence in the transcripts turned over, and had not even gone through that yet and calling for more evidence when they had no reason for it being needed was then denied by the judge and seen as a stalling or fishing expedition, which is not allowed in the process.
When and if the trump team ever has reason for more evidence from the 1/6 Committee pertinent to his trial case, it won't be denied.
