Trump to order Mexican border wall, curtail immigration

President Trump today will order the construction of a Mexican border wall, a move that begins a multi-day roll out of immigration actions that's also expected to include moves related to refugees and visas, reports the CNN reports quoting a White House official.

Trump will make the announcement during a visit to the Department of Homeland Security, reports CNN.

Trump himself hinted at Wednesday's move on Twitter, writing "Big day planned on NATIONAL SECURITY tomorrow. Among many other things, we will build the wall!"

Precise details of the executive action aren't known yet, but the Trump administration believes they can construct the wall through existing law, including the Bush-era Secure Fence Act, reports CNN.

Trump launched his campaign on a hardline immigration policy, proposing to build a "great, great wall" along the US-Mexico border and later to institute a "complete shutdown of Muslims entering the United States" until the US government could properly vet people coming in.

But as time went on, Trump's rhetoric on immigration began to change and, at times, soften.

His aides eventually walked back the Muslim ban to a ban on immigration from countries with widespread terrorism issues. And while Trump promised to deport all people in the country illegal throughout the campaign, Sean Spicer, his press secretary, said Monday that repealing President Barack Obama's two immigration executive actions were not the President's prime focus.

"First and foremost, the President's been very, very clear that we need to direct agencies to focus on those who are in this country illegally and have a record -- a criminal record or poses a threat to the American people," Spicer said. "That's where the priorities going to be."
