Much like he did in 2016, President-elect Donald Trump made border security the centerpiece of his 2024 campaign, promising to cut the flow of migrants and address the million who are already here.   His plan includes mass deportations, stricter laws, and banning sanctuary cities.   This past week, FOX News Rundown host Jessica Rosenthal spoke to Charles Marino, a senior adviser in President Obama’s Homeland Security Department about President Trump’s border agenda.   Marino explained the scale of the current border crisis and the logistical and legal challenges Trump may face enacting his policies once he takes office. The nationally recognized security expert also discussed what actions can be done to address the reported thousands of convicted criminals who are on Immigration Customs Enforcement’s non-detained docket. We often must cut interviews short during the week, but we thought you might like to hear the full interview.   Today on Fox News Rundown Extra, we will share our entire interview with border security expert Charles Marino, allowing you to learn even more about how President-elect Trump’s proposed solutions for the border crisis could be carried out.
