梅拉尼亚共和党大会讲话称赞丈夫川普是“了不起的领袖”

The Republican National Convention moves Tuesday to a focus on the economy, a day after Melania Trump told a prime time audience her husband Donald is "an amazing leader" and the only one who can deliver change for the United States.

Tuesday's speakers in Cleveland, Ohio include some of the party's most prominent figures, including House Speaker Paul Ryan and former presidential candidates Chris Christie and Ben Carson.

"If you want someone to fight for you and your country, I can assure you he's the guy," Melania Trump said.

The Slovenian immigrant has been largely unseen during the presidential campaign and used part of the address to tell her personal story.

But her speech prompted questions about its origins after journalists noted striking similarities in one passage to an address Michelle Obama gave at the Democratic National Convention in 2008.

There was no immediate comment from the Trump campaign about the similarities.
