Hard as it might be to believe, tens of millions of Americans have no idea who Mollie Tibbetts was. Or Laken Riley. Or Rachel Morin. Or Jocelyn Nungaray.

But unless Donald Trump says their names on Thursday during his first presidential debate with Joe Biden, those low-information voters will continue to live in blissful ignorance of these four murder victims — two college students, one mother of five, and one precious 12-year-old — each of whom was slain by illegal immigrants. (To this sad list we should add an anonymous 13-year-old girl who was kidnapped and raped 11 days ago in a park in Queens, New York, in a sickening assault that the illegal immigrant “suspect” says he recorded.)

Biden doesn’t want you to know their names because he knows that illegal immigration is among the utmost concerns of the American people as we enter election season, and he knows that the blood of these three women and this one girl is on his hands. And because Biden doesn’t want you to know their names, the mainstream media likewise doesn’t want you to know their names. This includes CNN, which is hosting the debate, and it includes the network’s two reliably left Trump-hating moderators, Jake Tapper and Dana Bash.

While it’s both difficult and unseemly to rank-order a group of murders, this latest one, that of a little girl, is both wrenching and blood-boiling. As the New York Post reports: “Police in Houston have arrested two migrants from Venezuela for the murder of 12-year-old Jocelyn Nungaray, who was lured away from home, then strangled and dumped in a bayou. One of the suspects crossed the border illegally less than a month before the shocking murder, and was released into the US after claiming he feared for his life if he was sent back to his home country, sources told The Post.”

Worse yet has been the mainstream media’s coverage. Take, for example, the Associated Press, which reported the news on Thursday night. As Fox News’s intrepid Bill Melugin noted, “Not only does AP not mention that both suspects are illegal aliens who were both recently caught & released at border, they don’t even mention that they are from Venezuela, which police publicly disclosed.”

This isn’t a one-off. Let’s remember how the AP covered Laken Riley’s murder. Rather than focusing on the fact that her murderer should never have been in this country, the AP’s headline read, “The killing of a nursing student out for a run highlights the fears of solo female athletes.”

No, the fear is of murdering-dog illegal immigrants killing our girls and women. And the outrage is being tamped down by the Democrat-aligned Trump-hating media.

We aren’t imagining this. As NewsBusters pointed out, the networks’ morning coverage spent 15 minutes on Justin Timberlake’s DUI arrest on Long Island, but zero minutes covering the illegal alien murders of Rachel Morin and Jocelyn Nungaray.

Let’s face it: The mainstream media is hiding these murders — and these murderers — from us.

The cable networks are even worse, if that’s possible. On MSNBC, they were actually laughing about Fox News’s insistence on covering the killings. They were laughing, that is, when they weren’t getting triggered by the use of the word “illegal” to describe the murderers.

As Fox News’s Mary Katharine Ham wrote in the wake of Laken Riley’s murder and the AP’s decision to make it a story about women jogging: “What they do is, they take a sample size of two tragic murders, Laken Riley and Mollie Tibbetts in Iowa a couple of years ago in 2018, and then they don’t mention that either one of them — the thread that actually connects those two — is that both suspects, one serving a life sentence, were illegal immigrants. Perhaps you’re missing the story because you’re trying to turn it into another story because you don’t want to deal with the fact that this reflects badly on the policies that are in place during this administration.”

It’s strange, isn’t it, that when our mounted Border Patrol agents were wrongly accused of whipping a group of illegal immigrants, that lie made its way around the world before the truth could get its pants on. Indeed, we all heard about it thanks to the AP and its corrupt co-conspirators. But when a 12-year-old Texas girl is abducted and murdered by a couple of illegal immigrants from a country that keeps popping up in crime reports all around the country, it’s crickets and tumbleweeds.

This week, the list of debate advice for Donald Trump will grow long and complicated and impossible to adhere to. My advice is simple: Say their names.
