Obama, today in Indiana:

“I think it was surprising to me that a high ranking, if not the highest ranking, member of Senator Clinton’s team would be engaged in business activities and lobbying that was directly contrary to the position Senator Clinton had taken,” he said.

But if one of his advisors had done the same thing?

“Let me put it this way: I’m not surprised that Senator Clinton found herself in an uncomfortable position as a consequence. And I know that if staff of mine were putting me in that kind of position, I would get rid of them.”

Hillary spokesperson Jay Carson's response:

“When Sen Obama’s top economic advisor told the Canadian government not to take his anti-NAFTA rhetoric seriously, he and his staff misleadingly denied that the meeting ever occurred, and then took absolutely no action,” Carson said in a statement. “It’s good to know he has a higher standard for our campaign than his own.”

That last barb was a pretty good line, Jay, though I'm sure lots of folks will be objecting to the Goolsbee-Penn comparison, since they're hardly of comparable stature within the campaigns and were engaged in different types of activities.

Late Update: Oh, and Penn was getting paid; Goolsbee wasn't.

Late Late Update: It's also worth noting, however, that Goolsbee was reported (though it's been disputed) to have been characterizing Obama's position, while Penn wasn't characterizing Hillary's position. Meanwhile, here's video of Obama:
