May be nothing but I just ran a diff on the Loreta Lynch transcript from https://intelligence.house.gov/UploadedFiles/LL32.pdf and from https://www.dni.gov/files/HPSCI_Transcripts/2020-05-04-Loretta_Lynch-MTR_Redacted.pdf and it says they differ.
Someone more knowledgeable about PDFs needs to look at them as I don't know enough about PDF to extract the text to find out where they differ.
