As the 145th Kentucky Derby is set to unfold on Saturday with a record-breaking guaranteed purse of $3 million, some are looking back at the horse racing world's last stint in national news: Santa Anita.

The intrigue: 3 of the horses racing on Saturday — Game Winner, Improbable and Roadster — are from Santa Anita Park, where 23 top-tier thoroughbreds died from unknown causes within 4 months, the Washington Post reports. When the death toll was 21, Axios reported that 7 horses died while racing on the dirt oval, 5 died during turf races and 9 died while training.

Where it stands: Trainers and jockeys interviewed by the Post emphasized that the Kentucky Derby will bring some normalcy back to the sport.

Facebook boycott organizers share details on their Zuckerberg meeting

Facebook is in the midst of the largest ad boycott in its history, with nearly 1,000 brands having stopped paid advertising in July because they feel Facebook hasn't done enough to remove hate speech from its namesake app and Instagram.

Axios Re:Cap spoke with the boycott's four main organizers, who met on Tuesday with CEO Mark Zuckerberg and other top Facebook executives, to learn why they organized the boycott, what they took from the meeting, and what comes next.

Civil rights leaders blasted Facebook's top executives shortly after speaking with them on Tuesday, saying that the tech giant's leaders "failed to meet the moment" and were "more interested in having a dialogue than producing outcomes."

Why it matters: The likely fallout from the meeting is that the growing boycott of Facebook's advertising platform, which has reached nearly 1000 companies in less than a month, will extend longer than previously anticipated, deepening Facebook's public relations nightmare.

House Minority Whip Steve Scalise’s PAC is inviting lobbyists to attend a four-day “Summer Meeting” at Disney World's Polynesian Village in Florida, all but daring donors to swallow their concern about coronavirus and contribute $10,000 to his leadership PAC.

Why it matters: Scalise appears to be the first House lawmakers to host an in-person destination fundraiser since the severity of pandemic became clear. The invite for the “Summer Meeting” for the Scalise Leadership Fund, obtained by Axios, makes no mention of COVID-19.
