Billionaire Democratic activist and donor Tom Steyer announced Tuesday that he will enter the 2020 presidential race.

Why it matters: Steyer, whose recent work has focused on impeaching President Trump, promised to sink at least $100 million of his own money into his campaign, via the New York Times, which could instantly make him a player in the race.

The big picture: Steyer essentially has no limitations on how much of his own money he can spend on his campaign. The NYT notes that Steyer "can be expected to deliver his message aggressively over the airwaves, potentially crowding out other competitors who may hope to raise their profiles with paid advertising."

What he's saying: As president, Steyer wants to reform the "broken political system" and combat climate change.

When Democrats next week formally nominate the daughter of an Indian immigrant to be vice president, it'll be perhaps the biggest leap yet in the Indian American community's rapid ascent into a powerful political force.

Why it matters: Indian Americans are one of the fastest-growing, wealthiest and most educated demographic groups in the U.S. Politicians work harder every year to woo them. And in Kamala Harris, they'll be represented in a major-party presidential campaign for the first time.

The cardiac threat coronavirus poses to athletes

Cardiologists are increasingly concerned that coronavirus infections could cause heart complications that lead to sudden cardiac death in athletes.

Why it matters: Even if just a tiny percentage of COVID-19 cases lead to major cardiac conditions, the sheer scope of the pandemic raises the risk for those who regularly conduct the toughest physical activity — including amateurs who might be less aware of the danger.
