Rep. Tom Rooney (R-Fla.) is the latest Republican who will vacate their House seat after this term. The five-term congressman initially supported Marco Rubio in the 2016 campaign, and later endorsed Donald Trump before un-endorsing him following the Access Hollywood tape, the Tampa Bay Times reports. Trump won Rooney's district by 27 points in 2016.

The U.S. government has agreed to buy 100 million doses of Moderna's experimental coronavirus vaccine for $1.5 billion, or $15 per dose.
Why it matters: The Trump administration, through Operation Warp Speed, has now bought initial batches of vaccines from Moderna, GlaxoSmithKline and Sanofi, Pfizer, Novavax, Johnson & Johnson and AstraZeneca before knowing whether they are safe and effective. The federal government also appears to own some of the patent rights associated with Moderna's vaccine.

Democrats from across the party — including some of the women on Joe Biden's vice-presidential shortlist — are championing his historic appointment of Sen. Kamala Harris as his running mate.
What they're saying: "Joe Biden nailed this decision," former President Barack Obama wrote in a lengthy statement. "By choosing Senator Kamala Harris as America’s next vice president, he’s underscored his own judgment and character. Reality shows us that these attributes are not optional in a president."
