"We needed this information rapidly, from the PRC, while the pandemic was still new."
That excerpt from the Presidential statement is quite true, but China and its internal politics prevented that from happening as early as it was needed. That is well known.
Generally, though, that linked Presidential statement is not very specific with respect to the information it is requesting - other than total openness and everything. The request sounds quite reasonable and is also quite understandable. (After all, who does not want to know?)
However, even though total openness could in principle possibly lead to an answer to the question as to the origin of the pandemic virus, it also might not lead to such an answer (as noted upthread). Sure, one should continue to attempt to investigate what happened in Wuhan, but those investigations will likely only substantively concern Chinese internal politics and the local Chinese leaders' desire not to admit to their national leaders that there was an outbreak in Wuhan. It won't concern a lab-leak theory which seems to not hold water - see below. (However, if you can personally dispute the (Robert Garry's) stated analysis of the genome, please tell me explicitly where the analysis is incorrect.)
Here's that discussion on the SARS-CoV-2 genome:
Here's another good discussion that frames the issue with background information:
