DHS hopeful Clarke denies plagiarism in master's thesis

MILWAUKEE (AP) — Milwaukee County Sheriff David Clarke, who says he's been appointed an assistant secretary in the Department of Homeland Security, has denied he plagiarized content in his master's thesis on homeland security, while the Naval Postgraduate School confirmed Sunday that it's reviewing the allegations.

The denial followed a CNN report Saturday saying Clarke, who built a following among conservatives with his provocative social media presence and strong support of President Donald Trump, failed to properly attribute his sources at least 47 times in his 2013 thesis, titled "Making U.S. security and privacy rights compatible."

The CNN report said Clarke lifted language from several sources, and footnoted those sources, but did not use quotation marks to show he had used passages verbatim, despite school guidelines saying that material quoted word-for-word must be set off with quotation marks, or presented as indented text for longer passages, and be followed with a proper citation.

Clarke said he would act as a liaison between DHS Secretary John Kelly and state and local government officials, including mayors and law enforcement, as well as people in the private sector.
