How much responsibility does Rep. Barney Frank have for the current financial crisis? That’s what a well-mannered Harvard Law wanted to know when the congressman stopped by the university this week. Except rather than engage the fella with a deserved response, the House Financial Services Committee chairman went on the defensive, belittling Joel Pollak’s question when, well, it’s one we would ask ourselves. On its face, Pollak’s question wasn’t loaded, but Frank interpreted it as such — probably because he’s faced the same criticism on the Hill for weeks. Now Pollak is loading ammo against Frank, heading to Fox News’ Greta van Susteren to revisit the encounter and, ugh, we find ourselves concluding this might actually be a fair and balanced segment.
