A week after becoming the first Latino and immigrant U.S. Homeland Security chief, Alejandro Mayorkas on Saturday reiterated his resolve to fight domestic terrorism, a massive threat that has plagued the United States.

“To see the insurrection, to see the horrific acts of January 6 were not only personally devastating, but … that created in me a commitment to redouble our efforts to fight hate and to fight one of the greatest threats that we face currently on our homeland, which is the threat of domestic terrorism,” Mayorkas told CNN in an interview that aired Saturday evening.

Mayorkas, who served as deputy secretary at the Department of Homeland Security (DHS) under Barack Obama, was sworn after the breach of the US Capitol by supporters of former Republican President Donald Trump on January 6.

In another bid to reverse the policies of the previous administration, the 61-year-old said the Biden administration was working with “due urgency” to end the Migrant Protection Protocols (MPP), which forced more than 65,000 asylum seekers back to Mexico to wait for U.S. immigration court hearings.

“We are looking at that as recently as earlier today,” he said. “The urgency of that also cannot be overstated.”

Talking about the efforts to beef up cybersecurity in the US after the recent hacks by the Chinese and Russian groups, Majorkas said the new administration was working with Congress to allocate additional funding to enhance the security of federal infrastructure and information systems, as well as through public-private partnerships, Reuters reported.
