PORTLAND — Independent Sen. Angus King of Maine said hard work remains for the federal government to get its fiscal house in order.

King appeared on NBC’s “Meet the Press” on Sunday, taking part in a round table discussion with 2012 Republican presidential candidate Newt Gingrich, Democratic Rep. Xavier Becerra of California, Washington Post columnist E.J. Dionne and former business executive Carly Fiorina.

King said President Barack Obama should call a group of people together and start negotiating the best way to cut spending and raise revenues.

He said he thinks Obama should call them up to the Camp David presidential retreat, “lock the door and say, ‘Let’s get it done.’”

King was sworn in last week as Maine’s newest senator, replacing Olympia Snowe.
