CNN’s John King called into Boston Public Radio on Tuesday to give his weekly breakdown of the week’s national headlines. King talked about forthcoming congressional hearings with Postmaster General Louis DeJoy, the first night of the Democratic National Convention, and what we can glean from polls about the current standing of presumptive Democratic presidential nominee Joe Biden.

John King is CNN’s chief national correspondent and anchor of “Inside Politics,” which airs weekdays and Sunday mornings at 8 a.m. on CNN.
