In hour one of Here & Now’s March 23, 2018 full broadcast, ABC News political director Rick Klein and Univision’s Enrique Acevedo join us to discuss the week’s political developments, including John Bolton being named President Trump’s new national security adviser, and the $1.3 trillion budget deal that Congress negotiated down to the wire this week. Also, we meet one man who was homeless in New York City for a period of time, and bucks many of the common assumptions about members of the homeless population. And 15 years ago this week, U.S. forces invaded Iraq, launching a controversial war that in some respects hasn’t ended. We speak with a former Marine who was there and is now writing about his experience.
