President Donald Trump's administration says it has gone 15 straight months without a single release at the border as of Thursday.
Homeland Security Secretary Markwayne Mullin's office says daily apprehensions at the border are down 94% compared to former President Joe Biden's administration and are at the lowest level seen in 30 years.
"Again this month, the results are clear: President Trump’s border security agenda is restoring order and putting the safety of the American people first," Mullin said in a statement.
"DHS remains focused on enforcing our immigration laws, securing the border, and ensuring those who enter our country illegally are removed swiftly. Thanks to the strong leadership of President Trump, we have the most secure border in history," he added.
'AMERICA FIRST' IMMIGRATION OVERHAUL BILL WOULD CODIFY TRUMP'S CAMPAIGN PROMISES ONCE AND FOR ALL
Meanwhile, seizures of contraband at the border in July were 26% higher than under Biden, with authorities seizing cocaine, methamphetamine, heroin, fentanyl, and marijuana.
U.S. Customs and Border Protection (CBP) also helped enforce Trump's tariff policies, flagging $23 billion in duties identified for collection in July alone.
"Clear policy, strong enforcement, and dedicated frontline personnel are delivering results at our borders," CBP Commissioner Rodney Scott said in a statement.
"With the support of President Trump and Secretary Mullin, CBP is securing our nation against illegal crossings, dangerous individuals, and illicit drugs while keeping lawful trade and travel moving. These results show what is possible when border security is treated as a national priority," he added.
The Trump administration is still moving to increase its immigration enforcement efforts. Last month, the House of Representatives moved toward codifying several of Trump's immigration orders.
The Permanent Trump Secure Border Act would criminalize visa overstays and increase penalties for unlawful entry, would effectively end "catch and release" policies by requiring most illegal migrants to be detained or returned while their cases are pending and tighten asylum eligibility and humanitarian parole, among other provisions.
The measure would also bolster the CBP by directing the DHS to modernize border facilities, expand staffing and workforce planning and deploy more surveillance technology, including drones, radar systems, biometric screening and DNA collection.
