From President Joe Biden on down, the administration is telling nonstop, bald-faced lies about the border crisis — while trying to stop the media from reporting the truth.

Biden insists the surge is normal, when it’s setting records. He insists it’s not because of his words and policies, when common sense, Mexican President Andrés Manuel López Obrador and the migrants themselves say the opposite. He also pretends it’s all his predecessor’s fault, with yet more lies about what President Donald Trump did.

And he claims most illegal crossers are being turned back, when officials on the ground report the reverse.

Oh, and he calls his approach compassionate, when it in fact brings suffering through the long trip north and then in this country, with children stuck in horribly overcrowded facilities while released adults swarm overwhelmed border towns. A 9-year-old girl drowned in the Rio Grande last week because of the message Biden is sending: If you get into the US, you can stay.

Homeland Security Secretary Alejandro Mayorkas insists the US-Mexico border is “closed” for everyone except migrant children seeking to enter the country alone. Solo minors are indeed accepted without question, but the recent immigrant surge, the worst border “challenge” in 20 years, goes far beyond that. Sheriff J.E. Guerra of a Texas border town told The Post that so many agents are being transferred from patrol duty to processing stations that “basically, the border’s open” to anyone.

Agents have been instructed to let groups of migrants pass through without so much as a court date because there simply isn’t room to detain them anywhere.

In Del Rio, Texas, where an average of 150 immigrants arrive daily, facilities have released 2,000 migrants into the country since February without a COVID test due to a lack of resources.

The surge is setting records by the week and month, with the eventual total certain to surpass the worst under the last two presidents. Over the span of a single week this month, Border Patrol turned away only 13 percent of the 13,000 border-crossers traveling in family units. Indeed, over 1,000 children and family units are crossing the border on any given day, and the feds expect crossings to double over the next month.

In February alone, more than 9,000 unaccompanied children crossed the border, up 63 percent from January and bringing the total since October to nearly 30,000.

Some 15,500 immigrant children are in federal custody, with 5,000 of those housed in facilities on the border (some of which are the very “cages” liberals condemned under President Trump). Even White House Press Secretary Jen Psaki admitted that these detention buildings are “not places made for children.”

Mayorkas, Biden and Vice President Kamala Harris have repeatedly tried to blame the chaos on the previous administration, but Biden’s policies are the ones separating families.

Trump had made significant progress toward securing the border, only for Biden to halt construction on his wall and end the “Remain in Mexico” policy. He also proposed a path to citizenship for the millions of illegal immigrants already here and reaffirmed the Obama Deferred Action for Childhood Arrivals program.

And Biden made an exception for Trump’s Title 42 order, allowing children to stay despite the health crisis of the pandemic. Indeed, the administration is releasing COVID-positive migrants by the dozens into the interior.

You can see why Team Biden has moved to restrict media access, even though left-leaning reporters focus mainly on the feds’ failure to help the migrants enough.

It’s amazing that they keep all these lies coming, but apparently they have no idea what else to do.

Be outraged, but also ask: How much else is the Biden administration lying about?
