The South Dakota Public Utilities Commission has stricken parts of a witness's testimony and exhibits in the application process for the Keystone XL pipeline. That action took place Thursday, Oct. 29, at the PUC's regular meeting. Cindy Myers is a registered nurse who says she followed PUC's instructions to prepare her testimony. But TransCanada attorney William Taylor says Myers violated rules of evidence. SDPB's Victoria Wicks reports.
