A speechwriter for Donald Trump's business took the blame for apparent plagiarism in Melania Trump's convention speech, saying she offered to resign over the error but was asked to stay by Mr. Trump. 

Meredith McIver is a staff writer for Trump's private company, not his presidential campaign, and issued her statement on Trump Organization letterhead.

McIver twice called the inclusion of language from Michelle Obama's 2008 speech "my mistake," seemingly contradicting the campaign's earlier insistence that no significant plagiarism occurred.

According to McIver, Mrs. Trump "always liked" the First Lady and passed on her convention remarks as an "inspiration" for her own speech. Somehow, the passage ended up in the final version largely unchanged.

"Over the phone, she read me some passages from Mrs. Obama's speech as examples," McIver wrote. "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 to Melania and the Trumps, as well as to Mrs. Obama."

McIver added she had offered to resign over the error, but Mr. Trump rejected it, chalking the incident up to "innocent mistakes."
