UPDATE Jan. 25 8:00 a.m.:
Trump is also expected to sign executive orders that would put a temporary ban on most refugees and suspend visas for citizens of Syria and other Middle Eastern countries, Reuters reports.
The order may be signed Wednesday or later this week. The exception to the refugee bans would include religious minorities avoiding persecution and would be lifted after "extreme vetting" procedures were in place.
I will be making my Supreme Court pick on Thursday of next week.Thank you!— Donald J. Trump (@realDonaldTrump) January 25, 2017
He said he would announce his nominee for the vacant Supreme Court seat on February 2.
ORIGINAL STORY: President Donald Trump will begin rolling out executive actions on immigration Wednesday, beginning with steps to build his proposed wall along the U.S.-Mexico border, two administration officials said. He's also expected to target so-called sanctuary cities and is reviewing proposals that would restrict the flow of refugees to the U.S., The Associated Press reported.
President Trump is expected to sign the first actions, including the measure to jumpstart the construction of the wall. Additional actions will be executed over the next few days, one official claimed. Trump is said to still be weighing the details of plans to restrict refugees coming to the U.S. The current proposal includes a minimum four-month halt on all refugee admissions as well as a temporary ban on people coming from some Muslim-majority countries, according to a representative of a public policy organization that monitors refugee issues.
Big day planned on NATIONAL SECURITY tomorrow. Among many other things, we will build the wall!— Donald J. Trump (@realDonaldTrump) January 25, 2017
On Tuesday night, President Trump tweeted:
President Trump campaigned to toughen U.S. immigration policies, including tighter border security and stemming the flow of refugees. He also called for halting entry to the U.S. from Muslim countries, but later shifted the policy to a focus on what he called "extreme vetting" for those coming from countries with terrorism ties. While the specifics of Trump's orders were unclear, both administration officials said Wednesday's actions would focus in part on the president's plans to construct a wall along the southern border with Mexico
He's also expected to move forward with plans to curb funding of cities that don't arrest or detain immigrants living in the U.S. illegally, which could cost individual jurisdictions millions of dollars.
Trump's statement that Mexico would pay for the wall was among his most popular proposals on the campaign trail, sparking enthusiastic cheers at his raucous rallies. However, Mexico has repeatedly said it will not pay for any border wall
Earlier this month, Trump said the building project would initially be paid for with a congressionally approved spending bill and Mexico will eventually reimburse the U.S., though he has not specified how he would guarantee payments. Trump will be meeting with Mexican President Enrique Pena Nieto at the White House next week.
As president, Trump can use an executive order to halt refugee processing. President George W. Bush used that same power in the immediate aftermath of the Sept. 11 terrorist attacks.
Currently, some immigrants caught crossing the border illegally are given notices to report back to immigration officials at a later date.
If Trump's actions would result in those caught being immediately jailed, the administration would have to deal with how to pay for jail space to detain everyone and what to do with children caught crossing the border with their parents.
