Dr. David Kessler, former FDA commissioner and chief science officer of the White House Covid-19 Task Force, talks with Rachel Maddow about the devastating effects of Donald Trump's cuts to HHS, not only in dismantling important services, but compromising U.S. medical and scientific leadership to a degree that may not be recoverable for decades.

Rachel Maddow looks at ways to understand the scope of the damage Donald Trump has done to the entire world economy, and reminds viewers where the tariff idea came from that has turned Donald Trump into a one-man global disaster.
