REDFORD, Mich. (AP) — President Barack Obama warned Monday that he "won't compromise" on his demands that the wealthiest Americans pay more in taxes, digging in on the chief sticking point between the White House and Republicans as they seek a way to avert the "fiscal cliff."

Obama brought his pressure-Congress campaign to the heart of industrial America, ripping lines from his own re-election bid as the nation inched closer to a perilous economic cliff. He said the country couldn't afford a "manufactured" crisis and pledged to cheering auto workers that he would fight to extend tax cuts for the middle class before they expire at year's end.

"That's a hit you can't afford to take," Obama declared.
