On the afternoon of January 27, 2017, after the U.S. President Donald Trump signed an executive order that would block the entry of refugees for 120 days, he said that the order, which also suspends immigration from seven predominantly Muslim countries, is part of his plan to impose "extreme vetting".
Vetting involves a set of processes for assessing the integrity of individuals in order to determine their suitability for public employment.
The process of vetting also requires the conducting of background checks that can involve a variety of inspections or examinations.
Trump called the procedures of vetting certain individuals trying to come into the U.S. would be put in place in a “totally extreme” process; during an interview with Fox News on Thursday. “We're going to have extreme vetting for people coming into our country and if we think there's a problem, it's not going to be so easy for people to come in anymore,” he said.
Successful vetting depends on access to information that is reliable and can be verified and proven to be accurate.
