(CNN) At least one passage in Melania Trump's speech Monday night at the Republican National Convention plagiarized Michelle Obama's speech to the Democratic National Convention in 2008.

Side-by-side comparisons of the transcripts show the text in Trump's address following, nearly to the word, the first lady's own from the first night of the Democratic convention in Denver nearly eight years ago.

The controversy quickly overshadowed the speech, which was to have been her introduction to voters. It focused on her immigration to the US and her love for her husband.

A Republican operative familiar with how the campaign was handling the speeches said a number of senior aides had a role, edited Melania's speech, suggested changes and provided guidance.

The Trump campaign released a statement on the speech after the similarities were uncovered, but the statement did not mention the plagiarism charge.

"In writing her beautiful speech, 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," according to Jason Miller, the senior communications adviser.

Earlier in the day, Melania Trump told NBC's Matt Lauer: "I read once over it, that's all, because I wrote it ... with (as) little help as possible."

Here is Trump, on Monday:

"From a young age, my parents impressed on me the values that you work hard for what you want in life, that your word is your bond and you do what you say and keep your promise, that you treat people with respect. They taught and showed me values and morals in their daily lives. That is a lesson that I continue to pass along to our son," Trump said.

And we need to pass those lessons on to the many generations to follow. Because we want our children in this nation to know that the only limit to your achievements is the strength of your dreams and your willingness to work for them."

And here is Obama, on August 25, 2008:

"And Barack and I were raised with so many of the same values: that you work hard for what you want in life; that your word is your bond and you do what you say you're going to do; that you treat people with dignity and respect, even if you don't know them, and even if you don't agree with them.

And Barack and I set out to build lives guided by these values, and to pass them on to the next generation. Because we want our children -- and all children in this nation -- to know that the only limit to the height of your achievements is the reach of your dreams and your willingness to work for them."

The reaction:

"(To be honest), I was more offended by just about every other speech than Melania's plagiarized paragraphs," former Obama speechwriter Jon Favreau jokingly tweeted as the accusations went viral hours after Trump's address.
