WASHINGTON - Presumptive US Republican presidential candidate Donald Trump's campaign has rejected accusations that parts of a speech the billionaire businessman's wife, Melania, delivered at the Republican National Convention were plagiarized from Michelle Obama’s 2008 Democratic convention speech.

Trump campaign chairman Paul Manafort said Melania Trump “hit it out of the park” on Monday night with her address on the first day of the Republican National Convention in Cleveland, Ohio.

“I thought Melania Trump hit it out of the park when she talked about her love of family, the feeling of an immigrant that comes to this country and succeeds,” Manafort said. “And I thought that the feeling she has towards her husband and her depiction of the real Donald Trump came through loud and clear.”

“There's no cribbing of Michelle Obama's speech. These are common words and values that she cares about her family, things like that,” he said when asked about the plagiarism allegations.

 “I mean, she was speaking in front of 35 million people last night. She knew that. To think that she would be cribbing Michelle Obama's words is crazy. This is once again an example of when a woman threatens Hillary Clinton, how she seeks out to demean her and take her down. It's not going to work.”

Meanwhile, Trump spokesman Jason Miller defended Melania from plagiarism allegations in a statement issued early Tuesday morning.

In addition, an actor who delivered a speech supporting Donald Trump at the Republican National Convention in Cleveland, Ohio, on Monday evening says he believes President Barack Obama is “absolutely” a Muslim. Antonio Sabato,  a former Calvin Klein model who also appeared on TV shows such as “General Hospital,” told ABC News that he does not believe Obama is a Christian, saying, “He’s with the bad guys.”

“I don’t believe the guy is a Christian, I don’t believe he follows the God that I love and the Jesus that I love. I think that he has had an agenda from the beginning,” Sabato said.

Sabato said the president’s last name is “not a Christian name, is it?” 

He claimed that Obama has “never talked about Jesus Christ once,” according to The Washington Post.

Earlier in the evening, during his convention speech, the Italian-born Sabato talked about the path he followed to American citizenship,

"I followed all the rules and finally became a naturalized citizen in 1996. Others who want to come to the U.S ... should follow the same moves!" he said to cheers.
