BYRON YORK: Rise in illegal crossings roils immigration debate. “What Schumer conceded, perhaps in an unguarded moment, is that the border remains quite porous, and the U.S. can expect “lots of millions” to cross illegally in coming years if nothing more is done. The disagreement on Capitol Hill, of course, is over what should be done, but Schumer’s off-the-cuff analysis provides a lot of material for Republicans pressing for a guarantee of greater security measures before millions of illegal immigrants are given legal status.”
