Update 1/25/17 4:20 pm:According to an eight-page document obtained by the New York Times, Trump's executive order will require more rigorous vetting on refugees trying to escape persecution and put a month-long ban on people entering the U.S. from Iraq, Syria, Iran, Sudan, Libya, Somalia, and Yemen. Furthermore, while a review of immigration screening procedures are taking place, there will be a 120 day suspension of letting refugees into America. When the review process is over, the U.S. will take 50,000 rather than 110,000 refugees a year.

Late last night, President Donald Trump tweeted that he had a "big day planned on NATIONAL SECURITY" for Wednesday. In addition to beginning work on the infamous wall on the Mexican border he promised to build during the campaign, Reuters reports that he is expected to put a temporary ban into place that would bar Syrian refugees and Muslim immigrants from certain countries from entering the United States.

Congressional aides who asked to remain anonymous told Reuters that Trump is planning to sign an executive order today that would block visas to anyone from Syria, Iraq, Iran, Libya, Somalia, Sudan, and Yemen. Although the temporary ban might be limited to these countries for now, it is important to remember that Trump did promise to place a temporary ban on all Muslims when he was running for office. Now is the time he might be proving that his Islamophobic words wasn't just campaign rhetoric.

Whether these executive orders will make America safer — or if they're even legal is up for debate. On Tuesday night, Nihad Awad, the executive director of the Council on American-Islamic Relations, tweeted that they "will not make our nation safer, rather they will make it more fearful and less welcoming."

The Independent also reports that Trump is getting significant preemptive backlash to his supposed plans. On top of lawyers questioning whether a ban on people from Muslim-majority countries is constitutional, a UN spokesperson stated to Reuters, "Any substantial delay in the relocation of refugees...would be highly concerning from a humanitarian perspective."
