共和党大会开幕日将着重于安全和移民问题

By the end of this week, the Republican Party will have officially nominated Donald Trump as its presidential candidate and presented its opening shot in the general election race that culminates with U.S. voters making their choice on November 8.

Monday's opening day of the party's convention in Cleveland, Ohio is focused on national security and immigration.

Speakers include former Governor of border state Texas Rick Perry, the mother of an American killed in Benghazi, Libya, several immigration reform advocates, former New York Mayor Rudy Giuliani, and Trump's wife, Melania.

In an interview with CBS' 60 Minutes broadcast Sunday night, Trump answered a question about the state of the world with an answer that is a likely preview of criticisms that will be directed this week at President Barack Obama and Democratic candidate Hillary Clinton.

"We need strength," Trump said. "Obama's weak, Hillary's weak. And part of it is, a big part of it, we need law and order. We need strong borders."

Trump has proposed building a wall along the U.S.-Mexican border as well as banning Muslims from entering the country. He softened slightly on the Muslim ban in Sunday's interview, suggesting he would focus more on people's country of origin.

"There are territories and terror states and terror nations that we're not gonna allow the people to come into our country. And we're gonna have a thing called "extreme vetting."
