 This is C-SPAN Radio coming up. Our coverage of day one of the Republican National Convention begins today. And starting at 1 p.m. Eastern time, a preview show of everything to expect throughout the day. Then before 2 p.m. Eastern time, just before 2 p.m. Eastern time, the first session of the convention begins. That's when we expect the roll call of delegates to select the Republican Party's presidential nominee.
