This evening, Barack Obama will headline the second night of the Democratic convention in Chicago, the city where his political career began. Like 2016, when he championed Hillary Clinton, he will attempt to use his political star power to help fuel the ascension of the country’s first woman president, and warn voters of the perils of a Donald Trump presidency.

This time, however, Obama no longer has the strength of the presidency behind him. Instead, he will attempt to reassemble the kind of coalition that powered his own rise behind the campaign of Kamala Harris.

Harris backed Obama’s long-shot campaign for president in 2007, when it was a political risk that few others would take. Now, Obama will return the favor. You can watch his speech, and others, live here.

Here’s what else to know:

• Democrats are newly hopeful that they can win control of Congress.

• Robert F. Kennedy Jr.’s running mate suggested that they might drop out of the race and endorse Trump.

• We took a look back at Chicago’s long history of political conventions, though photos.
