In a Tweet from the official White House X.com account the Trump Administration has claimed that "The Border is CLOSED.", and that February rate of illegal border crossings was a historic low.
Apprehensions are not equivalent to total crossings, but this may be an indicator of decreased crossing attempts. In a separate note the Department of Defense announce a deployment of a Stryker Brigade to the southern border of the United States to begin in the next few weeks.
It will be interesting to see if labor markets in construction, manufacturing, or agriculture report shortages in the coming months. Control of the border theoretically tighten certain labor markets, and produce higher wages for native workers in the United States or those willing to enter legally.
