Melania Trump's speechwriter has had her offer to resign rejected by the Trump Organization after she admitted a "mistake" in lifting passages from a Michele Obama oratory for Melania to use at the Republican National Convention.

Mrs Trump was heavily criticised for plagiarising a speech made by the outgoing First Lady in 2008, with entire phrases appearing also the same. The blame was then shifted onto Mrs Trump's speechwriters, while Donald Trump himself has blasted media bias, as well as the Clinton campaign.

Meredith McIver, an in-house speech writer for the Trump Organization, has now admitted she worked with Mrs Trump on the speech and apologised for the "confusion and hysteria" she has caused.

She added: "Over the phone, she [Mrs Trump] read me some passages from Mrs. Obama's speech as examples. I wrote them down and later included some of the phrasing in the draft that ultimately became the final speech. I did not check Mrs. Obama's speeches.

"This was my mistake, and I feel terrible for the chaos I have caused Melania and the Trumps, as well as to Mrs. Obama. No harm was meant."

McIver added that that Trump, now the official Republican presidential candidate, has rejected her offer of resignation as "people make innocent mistakes and that we learn and grow from these experiences".

The Trump campaign dismissed suggestions of plagiarism, describing the similarities as coincidental, adding similar phrases have also been used by Kid Rock, John Legend and even Twilight Sparkle from My Little Pony.

Jason Miller, senior communications advisor for the Trump campaign, also issued a statement praising Mrs Trump for "writing her beautiful speech".

Miller added: "Melania's team of writers took notes on her life's inspirations, and in some instances included fragments that reflected her own thinking. Melania's immigrant experience and love for America shone through in her speech, which made it such a success."
