World news: Donald Trump's chances of winning the United states election's are very high

WASHINGTON—

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."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," Trump said Monday.

"And Barack and I were raised with so many of the same values: like you work hard for what you want in life, that your word is your bond, that you do what you say you're going to do, that you treat people with dignity and respect," Obama said in her speech.

The Trump campaign issued a statement early Tuesday standing by the convention address.

"In writing her beautiful speech, Melania's team of writers took notes on her life's inspirations, and in some instances included fragments of her own thinking.  Melania's immigrant experience and love for America shone through in her speech, which made it such a success."Her speech did not have the fiery tones of many of the others who gave addresses Monday on the first day of the convention.  Retired Lt. Gen. Michael Flynn followed Trump's speech with sharp criticism of President Barack Obama and Democratic candidate Hillary Clinton.

"There will be no apologies for our American exceptionalism or leadership standing around the world," Flynn said.  "Wake up, America.  You cannot sit this one out."Former New York City Mayor Rudy Giuliani said a vast majority of Americans do not feel safe and warned terrorists, "We're coming to get you!"

Giuliani also mocked Obama's own address at the 2004 Democratic convention during which the then-Senate candidate said there is no liberal, conservative, black, white, Latino or Asian America, but a United States of America.

"It's time to make America one again," Giuliani said Monday.  "What happened to there is no black America, there is no white America, there is just America?"Senator Tom Cotton criticized Obama's efforts to end the wars in Iraq and Afghanistan during his term, saying the U.S. wants a leader "who speaks of winning wars and not merely ending wars."

In one of the final addresses, Senator Joni Ernst directed scorn at Clinton, saying the Democrat is "entirely unfit" to be president.  Clinton will be nominated at her party's convention next week.

Monday's speeches began with television personalities.
