Liberal and conservative backlash throws spending bill in doubt

Washington (CNN) - With just hours left to pass a spending bill that would avoid a government shutdown, a $1.1 trillion compromise deal in the House appears to be in trouble.

Usually the fight is between House Republicans and Senate Democrats. But this battle is different.

In fact, things got so weird Thursday, a Senate Democrat made a passionate appeal to tea party Republicans to reject the bill.

A compromise bill will never make members of both parties happy, but what is it about this one that is causing so much backlash?
