Who is Stephen Miller? Though officially chief speechwriter, he’s also the architect of the Trump administration’s anti-immigrant policies – travel bans, family separations, refugees in cages during a pandemic.

I talk with investigative reporter JEAN GUERRERO about her book, HATEMONGER: Stephen Miller, Donald Trump, and the White Nationalist Agenda.
