This afternoon we received this response from Karen Pensiero, assistant managing editor at the Journal:

"We fundamentally disagree with your assessment that our article 'Pressure Builds on Obama to Shake Up Inner Circle' was 'unsupported.' In fact, we were surprised that you took seriously the 'fabrication' claim by your anonymous contributor. As is clearly stated in our article, our premise came from 'interviews with Ms. (Dee Dee) Myers and other strategists in touch with the White House.' Those strategists told us that they 'expect more pressure for a complete West Wing overhaul,' as we clearly stated in the article. Not surprisingly, many of those high-level officials aren't comfortable with making those calls in public. But nonetheless, our reporting for this article was solid and complete. The remainder of the article laid out the reasons why pressure was building for a shake up in the White House inner circle. Please be assured that the Journal takes matters of fairness and accuracy very seriously. However, in this case we disagree with the premise of your contributor’s concern."
