Department of Homeland Security (DHS) acting Deputy Secretary Ken Cuccinelli praised the Trump administration’s Remain in Mexico program, which has sent back tens of thousands of migrants attempting to cross the southern border.

Cuccinelli—who was recently appointed to the —was on “Fox & Friends” Sunday talking about the White House’s efforts to deal with illegal immigration that has become a crisis on the U.S.-Mexico border.

Among the topics he talked about were his recent order to relocate National Park guards to help Border Patrol guards and the success of the Remain in Mexico Program.

Cuccinelli also pointed out that these National Park guards will have arresting powers, which will allow them to fully assist Border Patrol agents, who are often overwhelmed.

The Remain in Mexico program, also known as Migrant Protection Protocols, requires asylum-seekers who crossed through Mexico to reach the southern border to return and wait in Mexico while their claims are processed through the U.S. immigration judicial system, a process that could take months due to bureaucracy and the number of applications.

The program is ultimately designed to mitigate fraud by prohibiting asylum-seekers from escaping into the United States before their applications are judged.

Cuccinelli said the program, which was launched in January, has sent at least 60,000 migrants to Mexico.

“This is not just for people seeking asylum. It is also for people who’ve crossed the border illegally and they’re essentially on what we call a ‘detained docket.’  It means they are not going to be released until their case is heard, and so they’re waiting in Mexico as well,” he said.

“It’s been phenomenally successful, phenomenally helpful, and really we need Mexico to maintain it and expand it,” Cuccinelli added.

The appointment of Chad Wolf as Secretary and Ken Cuccinelli as Assistant Secretary of DHS – both supporters of “strong borders” – came when the Trump administration won a series of victories in the fight against the immigration crisis on the southern border.

According to a Fox report, border detentions have fallen by more than 65 percent since May as a result of tougher asylum policies, the construction of infrastructure on the border, and the signing of several agreements with countries like Mexico, Honduras, El Salvador, and Guatemala to contain migratory flows.

The construction of a wall on the U.S.-Mexico border was one of President Donald Trump’s great promises during his election campaign.

Although most of the media cover this issue from a negative angle, the real situation on the southern border is very dangerous and threatens the safety of all Americans, especially because of the entry of gangs like Mara Salvatrucha (MS-13), the trafficking of people (especially children) and the entry of illegal drugs, among other problems. These problems expose the need to strengthen border security, a task that the Trump administration has taken very seriously.
