A paper written by a newly hired special assistant to the University of Texas system’s Board of Regents is riddled with errors, according to an analysis by The San Antonio Express-News. The aide, Rick O’Donnell, wrote the paper, which questions the value of much of the research universities conduct, for the Texas Public Policy Foundation, a conservative think tank. A spokesman for the foundation took the blame for sloppy editing, and Mr. O’Donnell said he was “flabbergasted” by the errors, which the newspaper says include attributing quotes to the wrong sources and using inaccurate citations. The chairman of the Board of Regents has asked system lawyers “to expedite a careful review of the matter.” Mr. O’Donnell has worked for Jeff Sandefer, a business educator and major campaign contributor to Gov. Rick Perry, a Republican, who has been pushing universities to focus more on teaching and less on research.
