Here's your credible evidence.

Richard Grant takes issue with Governor Perry calling out the National Guard to secure our border. True, it is not the job of the National Guard, but when the President refuses to do his job, it becomes necessary to take matters into our own hands.

Richard says that he doesn't think it's fair that we call up these people because it will cost them personally and economically. That is true. Most citizens appreciate the sacrifices our armed forces make. But let's be perfectly honest about this -- they all volunteered. You can't take the benefits and then complain when you're called up. That's what the National Guard is for, and I'm sure those people understand that when they sign up.

Richard then worries about the economic cost and the loss of productivity for our communities. He says he's not willing to impose such a burden unless someone can produce credible evidence that not doing so gravely endangers all Texans.

OK, Richard, you asked for it. Many of these children are carrying communicable diseases -- TB, for example. I doubt any of these children have been vaccinated against measles, mumps, chickenpox -- they're being turned loose into our communities. I heard the other day that there is now a leprosy clinic in southern California. Look for all sorts of epidemics in the near future.

Teenage gang members for the El Salvadoran gang MS-13 are coming across the border. They must be treated the same as all the other children. So even violent criminals receive the same consideration and benefits. Attorney General Greg Abbott reported that, "The purpose of adding more resources on the ground is not to address the women and children, it’s to address the growing reality that a lot of people coming across the border are here for criminal purposes. They’re killing, they’re raping, they’re robbing, they’re doing all kinds of harsh criminal activity.”

Is that enough, Richard, or shall I give you some more evidence? Yes, it's costing Texas $12 million a month, but how much was Obama's initial request  -- not to secure the borders but to take care of these children? $3.7 billion. And that will be like bailing out the Titanic with a teacup if we don't stop the flow coming across the border.
