Mrs. Trump's address was otherwise distinct from the speech that Mrs. Obama gave when her husband was being nominated for president.

James DeVors of Aroma Park, another Trump delegate, said there should be consequences if someone intentionally lifted lines, "but it was just a small part of the speech".

But that's what the Trump campaign did early Tuesday after Melania Trump's address at the Republican National Convention in Cleveland.

In a press conference Tuesday morning, he alleged that presumptive Democratic presidential candidate Hillary Clinton's campaign was responsible for finding the clip.

PUSH BACK: Patricia Smith, whose son died in the Benghazi, Libya, attack, said she blamed Clinton, the former secretary of state, for his death and ended an emotional speech by suggesting Clinton should be in jail.

"To think that she would do something like that knowing how scrutinized her speech was going to be last night is just really absurd", Trump's campaign chairman Paul Manafort told CNN's Chris Cuomo on "New Day". "They taught and showed me values and morals in their daily life".

There is no end to the ironies that go with Melania Trump lifting Michelle Obama's thoughts on values like honesty, hard work and especially respect (and dignity) for others even if you don't know or agree with them.

"Think for yourself", he said.

At the convention, "he has to convince some of the doubters" that he "can deliver" on his promises, Kellyanne Conway, a senior advisor to the campaign, told reporters Tuesday. He did not explain how he arrived at the 93 percent figure.

Trump said on Monday:.and we need to pass those lessons on to the many generations to follow.

"We want our children and all children in this nation to know..." .

Plagiarism expert Jonathan Bailey writes on his website Plagiarism Today that although it's unlikely the similarities in the speeches were coincidental: They both "invoked the exact same values (hard work, word as your bond, and treating people with respect) in the exact same order with much of the same language", thus indicating last night's speech "borrowed heavily" from Obama's. The statement didn't mention Mrs. Obama.

Addressing Melania Trump's speech, her husband's campaign said a team of writers crafted the address after speaking to Melania Trump about her life.

Some tweets mocked Mrs. Trump as thanking her speechwriters, "Copy and Paste" and Milli Vanilli, a reference to the R&B duo exposed for lip synching others' vocals.

Margaret Pasquale, a middle school English teacher at Sacred Heart School, a Catholic school in Kingston, Mass., said that if one of her 7th graders had tried something similar, she would have rejected their paper and given the student a talking-to, but allowed them to make up the assignment. This kindness is not always noted, but it is there for all to see. "I have opportunities to talk with him very frequently about important issues and to help inform him about certain things".

Betsy Close, an OR state senator, took issue with how the then Melania Knauss, a Slovenian-born model, came into the country on a H1B visa, the programme used by high-skilled immigrants but also by Trump's modelling agency. Priebus praised Mrs. Trump for her "inspirational" remarks, particularly her story of immigrating from Slovenia.
