DHS Acting Press Secretary Statement on Border Wall Ruling

Border walls have proven to be extremely effective in preventing the flow of drugs and illegal aliens across our borders. Walls have worked in Yuma, Arizona and San Diego, California, where both areas have seen a 95 percent drop in attempted illegal border crossings.

Statement by Press Secretary Marsha Catron on Secretary Johnson’s Upcoming Trip to Mexico

On Oct. 14-15, Secretary of Homeland Security Jeh Johnson will travel to Mexico City to meet with Mexican President Enrique Peña Nieto, Secretary of Interior Miguel Ángel Osorio Chong, and Foreign Minister Claudia Ruiz Massieu regarding collective efforts to secure our borders, combat transnational criminal activity, and promote lawful trade and travel between the United States and Mexico.

Statement by Secretary Jeh C. Johnson Concerning H.R. 399, The Secure Our Border First Act of 2015

The “Secure Our Border First Act of 2015” voted out of the House Homeland Security Committee last night is not a serious effort at legislating border security – and its authors know it. The bill is extreme to the point of being unworkable; if enacted, it would actually leave the border less secure. The bill sets mandatory and highly prescriptive standards that the Border Patrol itself regards as impossible to achieve, undermines the Department of Homeland Security’s capacity to adapt to emerging threats, and politicizes tactical decisions.

An Open Letter Concerning Illegal Migration into the United States

In November President Obama announced a series of executive actions to fix the broken immigration system in this country. In December, the President announced that the United States government will begin a process of normalizing relations with Cuba. Both these actions are bold and historic changes to U.S. government policy. However, neither means a change in this government’s policy toward illegal migration. It is still the case that our borders are not open to illegal migration. In fact, we are taking additional measures to prevent illegal migration, now and in the future.
