"Even if he held one today, it would be the latest any new commander in chief has faced a formal question-and-answer session with the press corps in a century.... For 20 years, presidential aides have been telling me that the news conference is high risk, low reward... [But] it’s something a president can do in service of transparency and accountability even though it may not be obviously good for his political fortunes.... Presidential news conferences are hardly the apex of White House coverage. Reporters might get a sought-after moment on TV, or finally get an answer to a question they have been asking for weeks. But by definition, they don’t get scoops there..... Will reporters ask smart, probing questions on important issues and get answers that matter to Americans beyond the Beltway? Will Biden shed light on his next priorities, or which issues he thinks can wait until later in his presidency? We won’t know until this news conference happens."
That's from a WaPo piece titled "Biden is due for a news conference. But they can be risky."
I'd say WaPo is defining expectations as low as possible. "Will reporters ask smart, probing questions"? My expectations on that are very low. I think they will baby him as much as possible.
