President Biden said, "When I was vice president, the President asked me to focus on providing help needed to address the root causes of migration, and it helped keep people in their own countries instead of being forced to leave. The plan was working. But the last administration decided it was not worth it."
Facts first: Biden didn’t specify the program, but it’s true that the Obama administration set up a program to provide safer pathways to the United States that was later terminated by then-President Trump.
During his tenure as vice president, Biden led diplomatic efforts in Guatemala, Honduras and El Salvador after a growing number of unaccompanied minors from those countries began arriving in the US in 2014. The Central American Minors program was among the efforts.
The program allowed children under the age of 21 with parents lawfully living in the US to seek entry into the country from their places of origin if they did not qualify for refugee protections but were still at risk of harm. It served as an alternative for parents who might otherwise turn to smugglers to bring their children to the US illegally. While it might not have helped “keep people in their own countries,” it was intended to keep them from being forced to try illegal, and dangerous, methods of immigration.
There are mixed reviews on whether the program "was working," as Biden said, given the urgent situations some children were facing. In 2017, the Trump administration ended the program, making it difficult to assess its effectiveness since it had only been in place for a limited period of time.
The Biden administration has since announced it is restarting the program.
