CLEVELAND -- At least one passage in Melania Trump's speech Monday night seemed to be plagiarized from Michelle Obama's address 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 would-be future first lady's own from the first night of the Democratic convention in Denver nearly eight years ago.
Here is Melania 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 Michelle 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."
Journalist Jarrett Hill seems to have been one of the first to notice the similarities on Twitter.
He's a big fan of the Obamas, and told CNN over the phone that one particular line from Michelle Obama's 2008 speech really spoke to him: "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."
When he heard Melania Trump start saying "the only limit to your achievements," he knew something was wrong.
Hill said he then Googled Michelle Obama's speech and saw the similar lines.
"It was kind of a total recall moment," he said.
After he posted the comparison on Twitter, his tweet garnered 16,000 retweets.
University of Hartford communications professor Paul Siegel says that it's highly unlikely this was a coincidence. "Could it be by chance? No. It can't be. This is clearly lifted and it doesn't mean anybody did anything naughty. That happens all the time in the 21st century," he said, adding that many people find things on the internet and then forget where they found them.
Trump's presidential campaign said it has no plans to fire anybody on the campaign or to take any disciplinary action against anyone in the Melania Trump speech controversy, CNN learned Tuesday.
As campaign chairman Paul Manafort indicated at his morning news conference, the campaign's posture is to simply move on from this without addressing it any further.
Manafort denied allegations that Melania plagiarized a Michelle Obama speech on the first night of the Republican National Convention, calling the accusation "just really absurd."
"To think that she would do something like that knowing how scrutinized her speech was going to be last night is just really absurd," Manafort told CNN's Chris Cuomo on "New Day." He added, "There's no cribbing of Michelle Obama's speech. These were common words and values. She cares about her family," Manafort said. "To think that she'd be cribbing Michelle Obama's words is crazy."
Meanwhile, former Trump campaign manager Corey Lewandowski said Tuesday that whoever is responsible for writing the should be fired.
"Whoever was the staff person who wrote this speech should be held accountable and should be fired," Lewandowski told CNN's John Berman and Kate Bolduan.
Lewandowski, who is a CNN contributor, was fired from the Trump campaign last month.
Sources familiar with the campaign's handling of Melania's speech identify top Manafort deputy Rick Gates as the person inside the campaign who oversaw the entire speech process for Melania, but Gates is denying it.
When CNN's Jim Acosta asked Gates if he oversaw the Melania speech process, he said "absolutely not."
Two sources said that Donald Trump is furious over the episode.
New Jersey governor and Donald Trump ally Chris Christie defended the speech, saying, "There's no way that Melania Trump was plagiarizing Michelle Obama's speech."
"I just don't see it," Christie told CNN's Jamie Gangel in an interview Tuesday, adding later, "If we're talking about 7% of a speech, that was really, universally considered to be a good performance by Melania. I know her. There's no way that Melania Trump was plagiarizing Michelle Obama's speech."
Republican National Committee chairman Reince Priebus said at a Bloomberg Politics event Tuesday morning he'd "probably" fire whoever was responsible for including plagiarized quotes, though he added, "It all kinda depends on the circumstances and how these things are written."
The East Wing and White House declined to comment on the plagiarism story Tuesday.
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.
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."
Never gonna let you down?
In an even stranger twist, some on social media posited that Trump surreptitiously Rickrolled -- a common Internet meme involving singer Rick Astley -- everyone in the middle of her speech.
"He will never give up," she said of her husband. "And most importantly, he will never, ever let you down."
The chorus of the 80s classic sounds very similar: "Never gonna give you up/ Never gonna let you down/ Never gonna run around and desert you."
A bit of background -- Rickrolling is where you get someone to unwittingly click on a link to the video of the Astley song "Never Gonna Give You Up."
So, for example, if someone were to tell you to click here, saying it's another article about Melania Trump, and you click on that link, you would be taken to an Astley video and thus have been Rickrolled.
