As former South Bend Mayor Pete Buttigieg announced in his hometown that he was suspending his 2020 campaign, many of his former Democratic presidential rivals were lining up to pay tribute to him.

The big picture: Democratic front-runner Sen. Bernie Sanders and South Carolina primary winner Joe Biden were among those lauding Buttigieg. Even Sen. Amy Klobuchar — who clashed with Buttigieg over issues including immigration during a fiery Democratic primary debate in Las Vegas last month — had nothing but praise for him.

What they're saying:

Sanders told reporters he wanted to congratulate Buttigieg "for running a brilliant campaign. ... He is the first openly gay candidate for president of the United States and he did extraordinarily well," Sanders said, per Bloomberg. "And tonight, I just want to welcome all of his supporters into our movement, and to urge them to [join] us in the fight for real change in this country."

Biden tweeted, "Pete Buttigieg ran a historic, trail-blazing campaign based on courage, compassion, and honesty. We will be a better country for his continued service. This is just the beginning of his time on the national stage."

Sen. Elizabeth Warren tweeted, "Thank you. ... I know you'll continue giving back and serving our country for many years to come."

Former New York Mayor Mike Bloomberg tweeted, "[Buttigieg] ran a strong campaign that inspired audiences and made history. His dedication to serving our nation — as a mayor and veteran — reflected a love of country I deeply admire. Our party is stronger and our nation is better because of his run."

Klobuchar tweeted: "Pete Buttigieg has run an inspiring and historic campaign. I have so much respect for you ... and know there are great things ahead. And both John and I are big fans of Chasten!"

An FDA advisory panel on Tuesday voted 13-10 to endorse an antiviral pill developed by Merck and Ridgeback Biotherapeutics to treat adults at high risk of becoming severely ill from COVID-19, despite concerns over its effectiveness and safety.

Why it matters: Oral antiviral drugs designed to prevent or treat COVID-19 could be key pandemic-fighting tools, if proven effective, especially as new variants emerge. If authorized, the Merck drug, known as molnupiravir, would be the first treatment of its kind to be made available in the United States.

Fed signals it could yank economic support quicker as inflation sticks around

The Federal Reserve will consider pulling back economic support sooner "as the threat of persistently high inflation has grown," chair Jerome Powell said during a congressional hearing on Tuesday.

Why it matters: This is the biggest signal yet the Fed is backing away from its stance that soaring prices would be fleeting — a change that could shift its policies that underpin the economy.
