It was a bookend moment.
President Obama on Monday evening became the 10th American president to call on Helen Thomas at a White House news conference. And he was the first to call on Sam Stein, a reporter for The Huffington Post, whose Internet publication sprung to life during Mr. Obama’s candidacy.
. . .
Mr. Obama glided through the questions without making any obvious news. Then, he turned to Mr. Stein, 26, who last month became the White House correspondent for his publication.
“Are you willing to rule out — right here and now — any prosecution of Bush administration officials?” Mr. Stein said, asking whether Mr. Obama intended to endorse an investigation by a so-called Truth and Reconciliation Committee.
As he did with Ms. Thomas, Mr. Obama essentially bypassed the question, saying, “My general orientation is to say let’s get it right moving forward.”
It was not the answer but the very fact that he took a question from Mr. Stein that created a buzz and signaled yet another shift in the ever-evolving news media landscape.
