President Barack Obama is warning that it may be impossible to reach a deal with congressional Republicans on trimming the budget deficit even as he headed back to Capitol Hill to try to thrash out the issue with his opponents.
"Ultimately, it may be that the differences are just too wide," Obama said in ABC an interview that aired Wednesday.
Obama was set to go to Congress to meet Republicans in the House, with whom he has fought for two years over how to rein in the deficit and cut the national debt.
Obama and his fellow Democrats have pushed for more tax revenues from the wealthy, by raising taxes and by closing loopholes.
After agreeing to a tax hike on the rich in a year-end "fiscal cliff" deal, Republicans have insisted that Democrats do more to curb government spending and reform expensive social programs like Medicare for the elderly.
