Wall St. hypocrisy?

In the ongoing Wall St. reform battle between Republicans and Democrats words have been hurled back and forth in the attempt to define the opposition. Recently Senator Reid said something to the effect that Mitch McConnel and his ilk were cozying up to Wall St. Yet as this article shows, Reid has done some cozying of his own. An invitation to a financial firm on Wall St. for a Reid campaign fundraiser was discovered by Politico. Reid says it's not solicitation for campaign contributions from Wall St. PAC's, but doesn't it seem reasonable that someone on his campaign staff would have double checked the mailing list?
