A shake-up at the top of the Democratic ticket has pushed President Joe Biden’s speech to the first night of the Democratic National Convention rather than the last in which he was slated to accept the party’s nomination.

Biden is expected to give a prime-time address on the first day of the event, and programming that day is expected to focus on his political legacy and accomplishments from his administration. The convention is set to take place in Chicago from Aug. 19 to 22.
