Homeland Security Secretary Kirstjen Nielsen said Monday that her department may have been founded to combat terrorism, but its mission is shifting to also confront emerging online threats. It handles counterterrorism, election security and cybersecurity, natural disaster responses and border security — President Donald Trump's signature domestic issue. The president on Friday issued his first veto , to secure money for a U.S.-Mexico border wall. Nielsen said the department has introduced tougher screening systems at airports and is working with the State Department to notify other countries of stricter information-sharing requirements. She said the countries that work with the U.S. will make the world safer, and those that do not "will face consequences."
