President-elect Donald Trump's transition team is defending the syndicated talk show host Monica Crowley, named as a communications specialist for the incoming administration, against plagiarism accusations.

Crowley plagiarized vast sections of her books in more than 50 instances, a CNN KFile report has found.

Trump's transition team has dismissed the report as a 'politically motivated attack'.

The conservative author published 'What The (Bleep) Just Happened', a critique of Barack Obama's first presidency, in 2012.

The book, according to Monday's report, contains numerous sections lifted from outlets such as The New York Times, The Associated Press and Investopedia, without a bibliography or notes.

Crowley, set to serve as director of strategic communications for the National Security Council, appears to have taken passages from several columnists, news stories and even Wikipedia articles.

Trump's transition team has dismissed the latest accusations against Crowley.

The book (pictured), contains no bibliography or notes but some passages are strikingly similar to news stories, columns and even Wikipedia entries, the CNN report said

'Monica's exceptional insight and thoughtful work on how to turn this country around is exactly why she will be serving in the Administration,' a transition spokesperson told CNN in a statement.

'HarperCollins—one of the largest and most respected publishers in the world—published her book which has become a national best-seller. Any attempt to discredit Monica is nothing more than a politically motivated attack that seeks to distract from the real issues facing this country.'

One of the passages outlined in Saturday's report is what Crowley presented as a list of 'porkstatic spending items' from the 2009 stimulus package. But most of the items actually came from a podiatrist's 2004 website, and many came from a conservative list with some items dating back to the 1990s, CNN wrote.

Crowley also seems to have taken a large section from Investopedia, explaining Keynesian economics.

Eleven passages from the 2012 book also look identical to articles published in the National Review by Andrew C McCarthy, a friend of Crowley's.

Crowley was accused of plagiarism in 1999, after one of her Wall Street Journal columns looked similar to a 1988 story in Commentary magazine.

'Had we known of the parallels, we would not have published the article,' a Wall Street Journal editor's note read according to Slate.

Crowley denied the accusation, telling the New York Times at the time: 'I did not, nor would I ever, use material from a source without citing it.'
