Trump's first Oval Office speech will be followed by a Thursday visit to the southern border to highlight his demand for a barrier. White House press secretary Sarah Huckabee Sanders tweeted that he will "meet with those on the front lines of the national security and humanitarian crisis."

The administration is also at least talking about the idea of declaring a national emergency to allow Trump to move forward on the wall without Congress approving the $5.6 billion he wants. Vice President Mike Pence said again Tuesday that the idea of making such a declaration remains on the table.
