In her first major policy speech since launching her campaign for president, Kamala Harris today explained the core of her economic agenda and argued that she would protect the middle class for generations. She promised to fight big corporations and bring down the costs of food, housing and raising children. A centerpiece of her economic pitch is a new federal ban on price gouging on groceries.

Her newly unveiled economic plan mostly builds on policies embraced by President Biden, and wasn’t super-detailed, outside of a few policies.

The economy, and especially inflation, remain a top concern among voters, and polls suggest Donald Trump holds an edge on the issue. But Harris’s speech demonstrated her ease at explaining policy matters, especially compared to President Biden.

Harris delivered the speech in North Carolina, a state that Democrats believe she could potentially win, despite it not voting for a Democratic presidential candidate since 2008.

Here’s what else to know:

• Trump brought in Tulsi Gabbard, the former Democratic presidential candidate, to help prepare him for the debates. Harris’s debate team has someone playing the role of Trump.

• Tim Walz, Harris’s running mate, has faced criticism over Minnesota’s law on free tampons in schools. Here’s what it actually does.

• Trump described the Presidential Medal of Freedom as being “much better” than the Medal of Honor, because service members who receive the honor are often severely wounded or dead.
