Primary precinct convention minutes altered after the fact; a criminal offense?

2008 Texas Republican primary precinct convention minutes were altered after delivery to local party officials. Pages were altered and appended; specifically delegates for county convention were added (those added were neither present nor nominated by anyone who actually did attend the meeting). Is this a crime under Texas law? Seeing that this concerns a federal election, is this a crime under U.S. law? Anyone know any attorneys in Texas providing pro bono services to persons contemplating pursuing a criminal complaint (I've considered contacting Judicial Watch) against elected officials? Thank you for any istance.
