The Washington Times has announced that it will no longer run Sen. Rand Paul's (R-Ky.) regular columns, after one of them was found to have contained material that was apparently plagiarized.

Paul's Times column is the latest example in a string of plagiarism allegations. Paul's speeches and his 2013 book were previously reported to contain language that had appeared on Wikipedia, an AP report and on conservative Web sites.

A Paul adviser on Tuesday cited staff error for the lack of citations and failure to attribute the material. Paul is considered a leading contender for the 2016 GOP presidential nomination.

From the Times:

The newspaper and the senator mutually agreed to end his weekly column, which has appeared each Friday since the summer.

“We expect our columnists to submit original work and to properly attribute material, and we appreciate that the senator and his staff have taken responsibility for an oversight in one column,” Times Editor John Solomon said.

“We also appreciate the original insights he has shared with our readers over the last few months and look forward to future contributions from Sen. Paul and any other members of Congress who take the time to help educate our readers,” Mr. Solomon said.
