Speaking in Youngstown, Ohio, Aug. 15, GOP presidential nominee Donald Trump vowed to champion immigration reform that would "screen out any who have hostile attitudes toward our country or its principles." (The Washington Post)

On Monday, Donald Trump gave a speech at Youngstown State University in which he offered some more detail to his foreign policy proposals. Included in those details was more about his announcement last December that the United States should bar Muslims from entering the United States "until our country’s representatives can figure out what is going on." We've excerpted the portion of his speech related to that proposal and are annotating it, below. Click words highlighted in yellow to learn more.

The common thread linking the major Islamic terrorist attacks that have recently occurred on our soil – 9/11, the Ft. Hood shooting, the Boston Bombing, the San Bernardino attack, the Orlando attack – is that they have involved immigrants or the children of immigrants.

Clearly, new screening procedures are needed.

A review by the U.S. Senate Immigration Subcommittee has identified 380 foreign-born individuals charged with terrorism or terrorism-related offenses between 9/11 and 2014, and many more since then.

We also know that ISIS recruits refugees after their entrance into the country – as we have seen with the Somali refugee population in Minnesota.

Beyond terrorism, as we have seen in France, foreign populations have brought their anti-Semitic attitudes with them.

In Cologne, Germany, on New Year’s Eve, we have seen the reports of sexual violence and assault.

Pew polling shows that in many of the countries from which we draw large numbers of immigrants, extreme views about religion – such as the death penalty for those who leave the faith – are commonplace.

A Trump Administration will establish a clear principle that will govern all decisions pertaining to immigration: we should only admit into this country those who share our values and respect our people. In the Cold War, we had an ideological screening test.

The time is overdue to develop a new screening test for the threats we face today. In addition to screening out all members or sympathizers of terrorist groups, we must also screen out any who have hostile attitudes towards our country or its principles – or who believe that Sharia law should supplant American law.

Those who do not believe in our Constitution, or who support bigotry and hatred, will not be admitted for immigration into the country. Only those who we expect to flourish in our country – and to embrace a tolerant American society – should be issued immigrant visas.

To put these new procedures in place, we will have to temporarily suspend immigration from some of the most dangerous and volatile regions of the world that have a history of exporting terrorism.

As soon as I take office, I will ask the State Department and the Department of Homeland Security to identify a list of regions where adequate screening cannot take place. We will stop processing visas from those areas until such time as it is deemed safe to resume based on new circumstances or new procedures.

The size of current immigration flows are simply too large to perform adequate screening.

We admit about 100,000 permanent immigrants from the Middle East every year.

Beyond that, we admit hundreds of thousands of temporary workers and visitors from the same regions.

If we don’t control the numbers, we can’t perform adequate screening. By contrast, my opponent wants to increase the flow of Syrian refugees by 550% percent.

The United States Senate Subcommittee on Immigration estimates that Hillary Clinton’s plan would mean roughly 620,000 refugees from all current refugee-sending nations in her first term, assuming no cuts to other refugee programs. This would be additional to all other nonrefugee immigration.

The Subcommittee estimates her plan would impose a lifetime cost of roughly $400 billion when you include the costs of healthcare, welfare, housing, schooling, and all other entitlement benefits that are excluded from the State Department’s placement figures.

In short, Hillary Clinton wants to be America’s Angela Merkel, and you know what a disaster this massive immigration has been to Germany and the people of Germany – crime has risen to levels that no one thought would they would ever see. We have enough problems in our country, we don’t need another one.
