In his latest Fox Business interview, Donald Trump was asked about Vice President Kamala Harris’ potential running mates. “I don’t care,” the Republican responded. “Let them do whatever; they still want to have open borders.”

The “open borders” line was obviously gratuitous and unnecessary. It was also, of course, factually wrong. While we’re at it, let’s not forget that it’s also rather ironic given Trump’s direct role in killing a bipartisan compromise deal that would’ve imposed the conservative border policies the GOP claims to want. (As one Senate Republican conceded in January, the bipartisan deal, which was endorsed by the Border Patrol union, “would have had almost unanimous Republican support if it weren’t for Donald Trump.”)

But it was also poorly timed, as evidenced by the latest Arizona Republic report.

Arizona customs officers seized four million blue fentanyl pills weighing in at more than 1,000 pounds at the Lukeville border crossing in what is the largest single fentanyl seizure in the history of the agency responsible for securing the nation’s borders. U.S. Customs and Border Protection announced the seizure Thursday, but it happened a month earlier on July 1.

A CPB press release, issued yesterday, this seizure resulted from an American citizen who crossed the border, obtained the fentanyl, and allegedly tried to smuggle them into the United States by packing them to the frame of a sport recreational vehicle.

“While conducting a thorough inspection of the pick-up truck, trailer, and sport utility vehicle, CBP officers noticed anomalies throughout the frame of the trailer,” the statement added. “With the assistance of a CBP canine team, officers discovered 234 packages of drugs concealed within the frame of a trailer. The packages contained approximately 4 million blue fentanyl pills, which is the largest fentanyl seizure in CBP history.”

This roughly coincided with CBP officials also seizing 270 pounds of meth that suspected smugglers were trying to bring onto American soil.

It also coincided with fresh good news about the efficacy of the Biden administration’s border policies. As The New Republic’s Greg Sargent reported:

Unfortunately for Trump, unpublished [Department of Homeland Security] data shows that border encounters between ports of entry plummeted again to approximately 57,000 in July, according to an official familiar with the numbers. The data, which is preliminary until its official release in the coming days, was also leaked to CBS News and The New York Times. This is the fifth straight month of declining border crossings and the lowest monthly figure of the Biden administration. According to the Times, nine separate months during the Trump administration saw more border crossings than July under Biden did.

I realize that for the former president and his party, the repetition of the “open borders” phrase is habitual to the point of being mindless. For all intents and purposes, Republicans no longer know or care if the claim is true — or was ever true. It’s simply what the party has decided voters are supposed to believe.

But as the latest evidence makes clear, the GOP’s talking points are overdue for a rewrite.
