DHS confirmed that last week it provided the administration with a classified security report examining the vetting process for entry into the US. The report is likely to be the basis of Trump’s decision to act before Sunday’s deadline. It includes information on countries worldwide, meaning the president could even extend restrictions to locations not included in the original order.

Last week, Trump hinted he was prepared to extend and expand the ban. After a terrorist attack in London, he tweeted: “The travel ban into the United States should be far larger, tougher and more specific – but stupidly, that would not be politically correct!”
