President Trump has made his decision to withdraw from the Paris climate accord, according to two sources with direct knowledge of the decision. Details on how the withdrawal will be executed are being worked out by a small team including EPA Administrator Scott Pruitt. They're deciding on whether to initiate a full, formal withdrawal — which could take 3 years — or exit the underlying United Nations climate change treaty, which would be faster but more extreme.

Why this matters: Pulling out of Paris is the biggest thing Trump could do to unravel Obama's climate legacy. It sends a combative signal to the rest of the world that America doesn't prioritize climate change and threatens to unravel the ambition of the entire deal.

The other outliers: The only other two countries that aren't supporting the deal are Nicaragua and Syria.

How it happened: A letter from 22 Republican Senators (including Mitch McConnell) that called for a clean exit had reinforced Trump's instincts to withdraw, and the president had been telling confidants over the past week that he was going to pull out.

Trump's last comment on the issue, sent this morning on Twitter: "I will be announcing my decision on the Paris Accord over the next few days. MAKE AMERICA GREAT AGAIN!"

The two sides of America's coronavirus response

America's bungled political and social response to the coronavirus exists side-by-side with a record-breaking push to create a vaccine with U.S. companies and scientists at the center.

Why it matters: America's two-sided response serves as an X-ray of the country itself — still capable of world-beating feats at the high end, but increasingly struggling with what should be the simple business of governing itself.

Joe Biden introduces Kamala Harris in first joint appearance

Joe Biden formally introduced Sen. Kamala Harris as his running mate on Wednesday, telling a socially distanced audience in a Wilmington, Del., gymnasium: "I have no doubt that I picked the right person to join me as the next vice president of the United States of America."

Why it matters: Harris is a historic pick for vice president, becoming the first Black woman and first South Asian woman to be named to a major-party U.S. presidential ticket. "Kamala knows how to govern," Biden said. "She knows how to make the hard calls. She is ready to do this job on day one."
