US Border Patrol detained roughly 30,000 migrants attempting to cross the southwest border with Mexico in June, a 41 percent increase from the previous month, even as sweeping coronavirus-related border restrictions instituted by President Donald Trump remain in place.
Roughly nine in 10 of those caught crossing the US-Mexico border in June were single adults, according to statistics released on Thursday by US Customs and Border Protection (CBP). The number of single adults from Mexico detained at the border is on pace to rise this year, a shift away from arrests of mostly Central American families and unaccompanied children in 2019.
Trump, a Republican, faces reelection on November 3 and has made his efforts to restrict illegal immigration - including the construction of a wall on the US-Mexico border - a focus of his 2020 campaign. His presumptive Democratic challenger, former Vice President Joe Biden, would end the diversion of billions of dollars in military funding for wall construction.
As the coronavirus spread across the United States in March, the Trump administration restricted non-essential travel across the borders with Mexico and Canada to contain the disease. At the same time, the administration put in place health-focused rules that allowed US border authorities to rapidly expel migrants caught trying to cross illegally, arguing they could bring the virus into the United States.
The number of migrants caught by Border Patrol - particularly families and unaccompanied children - plummeted in April as the new measures went into effect and countries in the region initiated lockdowns.
Despite gradual increases seen both in May and June, the crossings still remain far below last year, when arrests peaked in May at 133,000.
