President Biden has used his first term in office to end many of the border and immigration policies of former President Donald Trump’s administration, actions some experts argue have led to the ongoing crisis at the southern border.

“By ending Remain in Mexico, encouraging asylum fraud, and mass paroling illegal aliens, Biden has provided entry to millions of inadmissible aliens,” Lora Ries, the Director of the Heritage Foundation’s Border Security and Immigration Center, told Fox News Digital. “By mass releasing them instead of following the mandatory detention statutes, Biden has allowed the millions to remain in the U.S. longer, knowing it is much harder to deport those who are not in detention.”

Ries’ comments come amid an ongoing crisis at the U.S. border with Mexico that shows no signs of slowing, with the latest U.S. Customs and Border Protection data showing Border Patrol encounters with migrants once again reached an all-time high towards the end of 2023, peaking at just over 300,000 in December.

By eliminating that policy, Morgan argued that it encouraged migrants who are actually moving for economic motivations to seek asylum in the U.S., adding significant strain to American border security.

“It deterred those individuals from risking their life and their financial well-being because they knew they were not going to be released in the United States,” Morgan said.

The second administration policy decision Morgan pointed to was Biden’s decision to end the Migrant Protection Protocol, more well known as the “Remain in Mexico” policy.

Morgan argued that the goal of many migrants who come to the border and claim asylum is to be released into the U.S., something that did not happen under the Remain in Mexico policy. Instead, asylum seekers were forced to wait on the other side of the border while their claim was processed, eliminating part of the incentive for those migrants who seek to abuse the asylum process and gain entry into the United States.

“The Remain in Mexico program didn’t deny anybody asylum,” Morgan said. “They simply said that you’re going to wait in Mexico while you’re going through asylum. We’re not going to release you in the United States to never be heard from again.”

Ries shared similar sentiment, arguing that reinstating both of those policies would go a long way to help alleviate the current crisis.

“Preventing asylum fraud includes requiring aliens to apply for protection in the first safe country in which they enter, not country shop to come to the U.S., and returning them to that first safe country,” Ries said. “It also includes fully implementing Remain in Mexico (and Canada), while getting back to the traditional U.S. Refugee Admissions process, where foreigners apply for refugee protection overseas, providing adjudicators better proximity to applicants’ documents and histories, and more time to thoroughly investigate and vet applicants.”

Instead, Ries argued that the Biden administration’s policies have resulted in severe consequences.

“America has open borders and has lost its sovereignty. We face serious national security threats, particularly from the 1.8 million known gotaways who evaded the Border Patrol during this Administration,” Ries said. “Americans have lost precious lives and public safety from the cartels, gangs, criminals, and drugs that have crossed the border.”

The White House did not immediately respond to a Fox News Digital request for comment.
