New Epstein revelations are sending shockwaves through the Trump administration as protesters gather outside the White House. The developments follow the House Oversight Committee's release of a letter allegedly sent from Trump to Epstein in 2003. The letter concludes with Trump allegedly writing to Epstein: "A pal is a wonderful thing. Happy Birthday — and may every day be another wonderful secret." MSNBC's Ari Melber reports, and is joined by former SDNY civil prosecutor Maya Wiley.
