President Donald Trump has repeatedly relied on HHS to help carry out his sweeping immigration agenda, and a new order that would limit visas to people who aren't "health care burdens" could be the latest dramatic change.

Mark Greenberg, who served as the acting assistant secretary for children and families during the Obama administration, sits down with POLITICO's Dan Diamond to discuss HHS' role in immigration and why he's so worried about Trump's recent order (starts at the 6:00 mark).

Then Scott Lloyd, the Trump appointee who led the HHS refugee office, joins Dan to discuss his experience after the administration began separating migrant families and thousands of children ended up in his office's custody (starts at the 25:45 mark).
