Joe Walsh, the former Tea Party congressman and 2020 Republican primary challenger to President Trump, said in an interview with BuzzFeed News that his past tweets calling former President Obama a Muslim are his biggest regrets on the platform.

Why it matters: While Walsh has apologized for some of his rhetoric, his inflammatory record is littered with controversy — including statements he has admitted were racist.

  • When asked about his tweets, specifically the one calling Obama a Muslim, Walsh told Buzzfeed, "That one bothers me the most. And I look at it and I say 'What the hell.'"
  • "It's the tweet I most regret. I let my policy differences with Obama cause me at times to be personal in my attacks against him. No excuse, and all I can say is that I'm sorry."

Between the lines: Walsh clarified that he doesn't think it's an insult to be called a Muslim. "There's nothing wrong with being Muslim. The insult was that I'm accusing him of lying because he has said he's Christian. That's why I was so wrong to do it."

  • Walsh also addressed his previous comments where he argued that he would not call himself a racist, but that "[he's] said racist things on Twitter."
  • "Those of us in the public eye have to account for things we've said. I think we're all capable of being racist at times, even if not purposely ... all I can do is apologize for [the remarks]."

Worth noting: In the interview, Walsh also said he believes climate change is real and that "it's an issue that the Republican Party needs a seat at the table with."

A Food and Drug Administration 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.
