The proposal follows his months-long call for a “total and complete” ban on foreign Muslims’ entering the U.S., which was also short on specifics.
Here’s what is known – and not known – about the plan.
Who Would Be Tested?
Trump said that the ideological tests would be aimed at people attempting to visit or live in the United States from “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,” he said Monday.
He argued that the “current immigration flows are simply too large to perform adequate screening.”
Trump named no countries but cited the number of immigrants from the Middle East as an example of the scope of the perceived problem.
What Would They Be Asked?
Trump did not give any examples of questions that would be asked, but said he wants to “only admit into this country those who share our values and respect our people.”
This is not the first time Trump has cited a past practice as the grounds for reintroducing certain reforms.
When he introduced his proposed Muslim ban, Trump cited three presidential proclamations that Franklin D. Roosevelt enacted after the attacks on Pearl Harbor in 1941.
“Those who do not believe in our Constitution or who support bigotry and hatred will not be admitted for immigration into our country. Only those who we expect to flourish in our country and to embrace a tolerant American society should be issued visas,” he said.
Other Factors at Play
Aside from the proposed ideological tests, Trump said one of his first acts as president would be to create a commission on “radical Islam” that he hopes would “include reformist voices in the Muslim community who will hopefully work with us.”
“We want to build bridges and erase divisions,” Trump said. “The goal of the commission will be to identify and explain to the American public the core convictions and beliefs of radical Islam to identify the warning signs of radicalization and to expose the networks in our society that support radicalization. This commission will be used to develop new protocols for local police officers, federal investigators and immigration screeners.”
Last week, when asked about the future of Guantanamo, he said that he would be “fine” with trying U.S. citizens in military tribunals, which would violate federal law.
He mentioned nothing about trying U.S. citizens at Guantanamo during his speech Monday.
Trump’s Previous Plan
In December, Trump called for a temporary “total and complete” ban on Muslims’ entering the U.S., but as time went on, he made more and more exceptions.
The day after his initial announcement, he clarified that U.S. citizens who are Muslim would be allowed back in the country. Then he said that Muslim politicians and athletes headed to the United States for sports competitions would also be exempt, though he did not specify what level of officials or athletes.
Three months later, he added another exception: his friends.
During an MSNBC town hall event in Wisconsin, Trump said he was getting calls from friends of his — “They’re very rich Muslims” — who he said told him that the proposed ban was “a great thing.”
Referring to those friends, he said, “They’ll come in,” and when host Chris Matthews pushed him on the question, Trump said, “They’ll come in. And you’ll have exceptions.”
In May, Trump backtracked, saying that it was a “temporary ban ... hasn’t been called for yet. Nobody’s done it. This is just a suggestion until we find out what’s going on,” he said during an interview with Fox News.
