WATCH: Homeland Security announces arrests of more than 100 undocumented immigrants

Department of Homeland Security Secretary Chad Wolf announced the arrests of more than 100 undocumented immigrants in California last week, part of “Operation Rise” targeting so-called sanctuary cities across the country.

Wolf said in the announcement that 96 percent of those arrested had criminal records or pending charges for crimes such as sexual assault, homicide, and domestic violence, among others.

“Political leaders who support Sanctuary City policies must stop putting politics over the public safety of their cities,” Wolf said in the news conference.

The action is the latest that underscores tension between the administration and sanctuary cities across the country, many of which have challenged some of Trump’s immigration policies in court.

Illegal immigration was among the threats on a 25-page “Homeland Threat Assessment” released by DHS this week, citing a number of perceived threats, including illegal immigration, natural disasters and foreign interference.

The report identifies “white supremacist extremists” as “the most persistent and lethal threat in the Homeland.” This comes amid racial tensions and protests around the country following the killings of Black people by police.
