Mitt Romney, who has been attacking former House Speaker Newt Gingrich and former Pennsylvania Senator Rick Santorum for being Washington insiders, hosted a $10,000-a-head event with lobbyists and industry executives today in Washington, D.C. The Democratic National Committee immediately jumped on the event, using it to paint Romney as a Washington insider himself. The event comes as questions of influence and lobbying are taking a large role in the campaign. Gingrich has faced questions for his work consulting for groups, such as drug companies, with Washington interests. Romney, the former Massachusetts governor, has been attacking Santorum for accepting earmarks when he was a senator.
