Jim Geraghty of National Review and Greg Corombos of Radio America welcome President Trump's order sending National Guard personnel to the southern border.  They explain why questions about whether Trump has such power are ridiculous but also hope the forces are not needed for long if lawmakers address the problem quickly and effectively.  They also get a kick out of "moderate" Virginia Democratic Sen. Mark Warner suddenly supporting some kind of "assault weapons" ban, proving once again Warner talks like a moderate but always ends up toeing the liberal line on virtually every issue.  And they shake their heads as Steven Spielberg suggests Indiana Jones could be a female character in future installments of the series.  Jim makes the point that it's a bad idea to recast roles so closely identified with a certain actor, and they both vent about the unmitigated garbage heap that was the fourth film in the Indiana Jones franchise.
