A Republican congresswoman from Texas has revealed that Border Patrol warned the Biden administration that overturning former President Donald Trump’s immigration policies would spark a spike in illegal crossings, and now agents are “at the end of their rope” trying to deal with the endless surge of migrants at the southern border.

Rep. Beth Van Duyne said she recently visited a federal detention center and found that children were “packed and stacked on the floor” of the center that she described as a “processing plant.”

She said a center built to house 250 people has 5,700 people in it.

“You’ve got customs and border folks who are at the end of their rope. They’re doing what they can but they’re also very frustrated, realizing that they had actually warned this administration what would happen if they decided to push back on policies that were put in place by the previous administration that were working,” Van Duyne said Tuesday during an interview on “Fox & Friends.”

In a Twitter post, she linked to a video taken at the center that showed the floor full of migrants covered by foil blankets with room barely enough to roll over.

She wrote that President Biden refused to heed the warnings of Customs and Border Patrol.

“Now, thousands of children are crammed into profoundly inadequate holding facilities as a direct result of Biden’s reckless actions,” she posted. 

Biden, upon entering the White House in January, began signing a raft of executive orders rolling back his predecessor’s immigration policies, including stopping construction on the border wall, protecting the so-called “Dreamers” from being deported, and reversing the Remain in Mexico policy that forced asylum seekers to wait in Mexico while their legal process plays out.

He also signed executive orders creating a task force to review family separations at the border and to examine federal agencies for policies that create “barriers to our legal immigration system.”​

The actions immediately prompted criticism that opening the border would release a flood of migrants heading to the US. ​

Van Duyne said the Trump administration’s policies were effective.

“They were keeping them in the first safe country that they came to and what we’re seeing is a massive surge now at the borders​,” she said.

“I​nstead of actually reversing policies that have caused this surge​, w​hat they’re actually doing is they are forcing thousands and thousands of kids to make this journey and they’re setting up decompression centers across the country​,” Van Duyne continued. ​​
