Every day at 7 a.m., President Andrés Manuel López Obrador strolls onto a stage in Mexico's National Palace and speaks almost nonstop for sometimes more than three hours. López Obrador’s morning media briefings, known as "las mañaneras," have provided him with a direct line to his political base, broadcast live on government and local news channels, and streaming online.
