Instead of using quote marks to reference his sources, Clarke apparently lifted language from other media and credited them in footnotes. But the thesis failed to use quotation marks where Clarke used passages verbatim, which breaches school guidelines, the network said.
CNN reports Clarke lifted passages from former President George W. Bush's book "Decision Points", the 9/11 Commission Report, reports from the Pew Research Center and a Washington Post article, among other sources.
Without commenting on the claims in their reporting, Sheriff David Clark snarled at the CNN team that says he plagiarized repeatedly almost four dozen times in his master's thesis.More news: Top Gun 2 movie is happening, Tom Cruise confirms
Raw Story reported that among the sources that Sheriff Clarke allegedly plagiarized from was a 2011 ACLU report on the need to overhaul secrecy laws, and an ACLU report from 2007 on 'fusion centers.
Clarke's thesis text was quickly removed from the school's website, as is its policy when a thesis is under scrutiny for plagiarism. After the allegations were revealed, Clarke took to Twitter and called reporter Andrew Kaczynski a "political hack" and "a sleaze bag".
A Sheriff's Department spokeswoman, Fran McLaughlin, told the newspaper that Clarke followed the school's system for writing papers and that the CNN report was biased. However, later on, a spokesperson for the Department for Homeland Security denied an official announcement had been made about any such development.More news: Sicily Open Soderberg, Hoey lead after flirting with 59
During the 2016 presidential race, Clarke was a close ally of Trump and had praised him since the president took office in January. Clarke has become a controversial figure for comments including calling Black Lives Matter a hate group. In September, the death of Terrill Thomas - one of four at the jail in one year - was ruled a homicide.
Last month, prosecutors said an inmate in solitary confinement had endured seven days without any liquid, lost 35 pounds and grown weak and quiet before he died inside his cell a year ago.
"I've never met Clarke, but based on his inflammatory rhetoric, along with the cloud hanging over his tenure in Milwaukee, I'll just come right out and say it: He's not fit to serve at the agency tasked with domestic security for all Americans", Kayyem said.More news: Miley Cyrus Says 'Malibu' Isn't a Typical Love Song
