A jury does not generally review each piece of evidence to determine whether the evidence is "valid" or not.

This evidence was already introduced at trial (in support of the conspiracy charges, since the campaign financing charge was dropped back in August). This means that the judge already reviewed it and deemed it to be valid, admissible evidence. (That happens before a trial, not after it, though in some cases may happen during a trial with the jury excused from the courtroom.)

It's weird to blindly believe OpenSecrets, which also does not link to supporting documents, while disbelieving widely-reported news reporting that has been covered for the past year...without any refutation by the Republican beneficiaries of SBF's donations.
