Homeland security secretary nominee Kristi Noem said in her confirmation hearing Thursday that on her first day in office, she would shut down an app that asylum-seekers use to enter the country.

South Dakota Gov. Kristi Noem, President-elect Donald Trump’s pick for Department of Homeland Security secretary, vowed Friday to immediately halt the mobile app that lets migrants register to enter the US.

South Dakota Gov. Kristi Noem told lawmakers that she intends to end the use of the CBP One on the first day the Trump administration.

President-elect Donald Trump's choice for Homeland Security secretary portrayed illegal immigration as an "invasion" and the U.S.-Mexico border as a "war zone" during a U.S. Senate confirmation on Friday where she pledged to back Trump's hard line on immigration.

So far, Kristi Noem appears to have strong backing from GOP senators who will be crucial to her confirmation as head of the Department of Homeland Security.

Ahead of the inauguration, migrant shelters south of the Rio Grande are far from full, a reflection of the tougher measures imposed on both sides of the border.

But another major issue Noem plans to tackle is cybersecurity infrastructure, including reigning in the recent anti-misinformation efforts by the Cybersecurity and Infrastructure Security Agency (CISA), which she says is a deviation from its core mission and an endangerment to Americans’ civil liberties.
