According to some reports, the President said this yesterday as he unveiled his actions on border and national security.
He has indicated temporary ban on immigration from Muslim countries deemed a 'threat to national security'.
Trump will also sign other domestic immigration enforcement measures that will include targeting sanctuary cities that decline to prosecute undocumented aliens.
The president posted a tweet on Tuesday evening signaling that major announcements were in the offing.
'Big day planned on NATIONAL SECURITY tomorrow (Wenesday)', Trump tweeted.
'Among many other things, we will build the wall!'
The new Trump directives will also stop most refugees including those from Syria coming to America while vetting processes are reviewed.
The one exception is religious minorities fleeing persecution – which would apply to Christians fleeing Syria and other Muslim majority countries.
In total the 6 immediate actions are as follows: Release of funds toward the construction of a wall along the southern border; Target so-called 'sanctuary' cities that decline to prosecute undocumented aliens; Institute a four-month freeze on admission of all refugees.
Others are Temporarily ban nationals from Muslim-majority countries that are 'terror prone'; Halt visas to people from Syria, Iraq, Iran, Libya, Somalia, Sudan, and Yemen; Grant exceptions to Christians and other minorities fleeing Muslim persecution.
