What Donald Trump omits in his attack on Joe Biden about border security

Former President Donald Trump said that the Biden administration has created a "national disaster" at the border by ditching Trump’s immigration policies. 

"We proudly handed the Biden administration the most secure border in history," Trump said in a March 21 statement. "All they had to do was keep this smooth-running system on autopilot. Instead, in the span of just (a) few weeks, the Biden administration has turned a national triumph into a national disaster." 

Trump was responding to comments on the Sunday news shows by Homeland Security Secretary Alejandro Mayorkas who pointed the finger back at the Trump administration for the border woes.

"The entire system under United States law that has been in place throughout administrations of both parties was dismantled in its entirety by the Trump administration," Mayorkas said on ABC This Week.

We found that the situation at the border is more complicated than either Trump or the Biden administration is indicating. Trump’s claim that the border was the "most secure" and "on autopilot" is a significant exaggeration. 

We found there is no simple metric to determine if Biden inherited the "most secure" border. Some cite miles of barriers, while others use various apprehension figures. 

"A secure border is really about definitions, and each side has their own definition of secure," said Laura Collins, director of the George W. Bush Institute-SMU Economic Growth Initiative.

Trump’s office didn’t respond to our emails asking what metric he was citing on border security. When Trump said near the end of the campaign that "we achieved the most secure border in American history" he cited the number of miles of border barriers that were built. But most of the miles were to replace existing structures, including in low-traffic areas. 

Another metric that Trump highlighted in May was apprehension numbers on the southwest border. Immigration experts have told us that high apprehension numbers could be an indication of effective border enforcement, others say low apprehension numbers are a sign that U.S. policies are working to deter illegal immigration in the first place.

Some experts point to the border apprehension rate, which is the proportion of attempted border crossers apprehended. The Department of Homeland Security’s August border security metrics report showed that the apprehension rate in fiscal year 2016 — Obama’s last full year — was the highest of any year between 2000 and 2018. 

So by that metric, the border was most secure in 2016, said Jessica Bolter, an analyst at the Migration Policy Institute. But the federal government hasn’t yet released more recent data, so we can’t use the apprehension rate to evaluate Trump’s claim that he handed off the most secure border to Biden.

Finally, due to the barriers and other deterrents at the border, unauthorized migrants largely enter at ports of entry and overstay a visa or turn themselves in and request asylum. That’s why miles of the border fence don’t tell us much about the status of border security. 

While Trump presents the border surge as a "disaster" under Biden, the spike in migrants, especially unaccompanied minors, started in the spring of 2020 during the Trump administration and generally continued to climb each month. The numbers of migrants apprehended at the border rose between January and February, but it’s still less than the surge in May 2019. And in February, most of the encounters that Customs and Border Protection recorded at the border resulted in quick expulsions under the same public health-related authority that was invoked under the Trump administration.

Besides U.S. policy, factors that drive migrants to leave their home countries have included economic havoc caused by hurricanes and the pandemic, and yearslong problems associated with violence. The numbers of migrants arriving at the border also tend to spike in the spring and summer months.

The ship that struck a Baltimore bridge “was cyber-attacked.”

When Biden took office, there was a pent-up demand to cross the border due to asylum seekers who were waiting in Mexican border towns because of Trump’s "Remain in Mexico" program and pandemic-related border closures. 

The Biden administration has repeatedly said that the border is closed. But it has made some policy changes, such as choosing not to expel unaccompanied children who cross illegally, even though it has the legal authority to do so.

Trump said Biden could have operated on autopilot, but experts said each administration must examine legal rulings and current conditions. 

"There is no such thing as 'autopilot' in immigration," said Susan Martin, an immigration expert at Georgetown University. "I don't see how Biden could have maintained Trump's policies, given the outcome of the election and the shifting situation on the border."

The Trump administration’s asylum policies on the border were also challenged in court.

"Operating on autopilot might have been a problematic policy because it involved denying people their ability to lodge an asylum case," said Josiah Heyman, director of the Center for Inter-American and Border Studies at the University of Texas at El Paso

Because Congress has failed to reach agreement on major immigration policies, that leaves it up to each new presidential administration to issue orders, set priorities and use words to convey a tone about immigration. 

"The border surge is just the latest symptom of a broken immigration system," Collins said. "Congress needs to do the hard work of modernizing our immigration system and adopting an ‘all of the above’ border policy that anticipates future crises and has the flexibility to adapt to changing circumstances."

Trump said "we proudly handed the Biden administration the most secure border in history. All they had to do was keep this smooth-running system on autopilot."

While Trump promoted building a wall, some metrics suggest Trump didn’t attain the most secure border in history. And Trump ignores that the surge started in the spring of 2020 when he was still in office. 

He also grossly oversimplified how the immigration system works. It’s not as straightforward as keeping it on "autopilot." 

Biden’s actions and tone on immigration play a role in migration, but so do other factors such as ongoing economic and social havoc in Central America.

We rate this statement Mostly False.
