Newly sworn-in Congressman Tom Marino is one day into the job, and already under fire.

America’s New Majority, a fundraising group which comprises Marino for Congress among other GOP campaign committees, held a $50,000 “Swearing In” party last night in honor of the Republican House Majority. Critics on the left and the right charge that the event contradicted Republicans’ core message in 2010.

“If incoming GOP freshmen were hoping to bring fiscal responsibility and “family values” to Washington, they may have gotten off to an interesting start with a big party in the works,” quipped conservative writer Matt Lewis.

“In the latest example of Republican hypocrisy, incoming U.S. Rep. – Elect Tom Marino will begin his career in Washington by taking money from the special interests he claimed to oppose on the campaign trail,” said Michael Czin, a spokesman for the DNC. “Before he is even sworn into office Marino will schmooze with lobbyists paying $50,000 at a lavish Washington hotel.”

“House freshman throws a party – and GOP cringes” read yesterday’s headline on Politico. It certainly wasn’t a welcome one for the GOP.

But Democrats should tread lightly with this line of attack. In 2006 Nancy Pelosi took heat for when she headlined a $1,000-per-plate fundraiser  – on the same day she inherited the Speaker’s gavel.

At the time of publication, the office of Congressman Marino had not returned requests for comment. It was unclear whether Marino attended the event in person, but the Sunlight Foundation’s Political Party Time blog listed Marino as a participant.
