CNN can't figure out Trump's wall proposal

CNN seems to believe President Trump has changed positions on his proposal for a wall along the southern border, though his rhetoric on the subject has remained almost entirely unchanged going back to before he won the Republican nomination.

The White House and Congress geared up this week for negotiations on sweeping immigration reforms, which Trump has said must include funding to begin construction of the wall. In media interviews, administration officials have said that the wall would be just one part of broader security measures, including enhanced technology and funding for more patrol agents.
