Sen. Evan Bayh (D-Ind.) took a shot last night at some of his Democratic colleagues who he says don't care enough about the deficit.

Bayh, who voted against his party's omnibus spending bill this weekend and has urged President Obama to veto it, criticized members of his party for an increase in domestic discretionary spending.

"I think for some of them, it's that they don't pay as much attention to the deficit. They just don't focus on economics," he told Fox News's Greta Van Sustren.

"For some others there are projects in the bill they like," he added, referring to earmarks.

The omnibus bill passed the Senate with the support of most Democrats and three Republicans. Bayh, Claire McCaskill (D-Mo.) and Russ Feingold (D-Wis.) were the Democrats to vote no.

Bayh wants Congress to establish an independent comimssion to make recommendations on reining in entitlement spending to reduce the deficit. Critics say that's an abdication of Congress's responsibility.
