Former President Donald Trump on Friday went after President Joe Biden, accusing his successor of prompting a “spiraling tsunami” of crossings at the U.S.-Mexico border.

In an emailed statement, the 45th president blamed the current 46th for the surge in border crossing, which has spurred the opening of a pair of two overflow facilities for unaccompanied migrant children.

“Our border is now totally out of control thanks to the disastrous leadership of Joe Biden,” Trump wrote in a lengthy statement. “Our great Border Patrol and ICE agents have been disrespected, demeaned, and mocked by the Biden Administration.”

“A mass incursion into the country by people who should not be here is happening on an hourly basis, getting worse by the minute. Many have criminal records, and many others have and are spreading covid. Interior enforcement has been shut down — criminals that were once promptly removed by our Administration are now being released back onto the street to commit heinous and violent crimes,” Trump said.

Here, the former president is referencing the recently reported release of migrants who had tested positive for COVID-19 in South Texas.

“The spiraling tsunami at the border is overwhelming local communities, depleting budgets, crowding hospitals, and taking jobs from legal American workers. When I left office, we had achieved the most secure border in our country’s history,” Trump continued. “Under Biden, it will soon be worse, more dangerous, and more out of control than ever before. He has violated his oath of office to uphold our Constitution and enforce our laws.”

On Firday, White House Press Secretary Jen Psaki fired back at Trump’s statements.

“We don’t take our advice or counsel from former President Trump on immigration policy, which was not only inhumane but ineffective over the last four years,” she said. “We’re going to tread our own path forward and that includes treating children with humanity and respect and ensuring they’re safe when they cross our borders.”

Biden notably stopped construction of his predecessor’s signature border wall along the southern border. In February also, the president started to phase out the “Remain in Mexico” policy, under which around 71,000 Central American asylum applicants were awaiting rulings in Mexico. In some circumstances, asylum seekers who are permitted to wait on rulings inside the United States can receive work permits while they wait.

Back in January, border agents apprehended nearly 78,000 people, an increase from 36,679 in January of last year. Furthermore, each week last month, around 2,200 unaccompanied children were reported to have crossed the border.

On top of loosening Trump administration rules, Biden issued an order affirming the 2012 Deferred Action for Childhood Arrivals (DACA) program, which provides work permits and shielding from deportation to individuals brought to the United States illegally as minors, known as “Dreamers.” He also put forward legislation that would establish an eight-year path to citizenship for the estimated 11 million undocumented immigrants residing in the country.

Conservatives have criticized Biden’s proposed path to citizenship, arguing that the allure of citizenship would inspire more migrants to cross the southern border.

“I had a great relationship with Mexico, and its wonderful president, but all of that has been dissipated by the gross incompetence and radicalism of the people currently in charge. The Remain in Mexico Policy was incredible, but immediately abandoned by Biden, probably because it worked so well,” Trump also said in his statement.

“Likewise, our Safe Third Agreements in Central America were extraordinarily successful, so Biden foolishly ditched them too,” he continued. “We stopped payment of the hundreds of millions of dollars paid to them and then developed an excellent relationship that made our country and their countries more secure.”

The former president also claimed that the current administration has “given the smugglers and traffickers effective control of our border” and anticipated that the border crisis would only worsen.

“There has never been a time on our southern border like what is happening now but more importantly, what is about to happen,” Trump said.

“Now that Biden has implemented nationwide Catch-and-Release, illegal immigrants from every corner of the Earth will descend upon our border and never be returned. You can never have a secure border unless people who cross illegally are promptly removed.”
