CHARLOTTE -- As expected, the national debt topped the $16 trillion mark today.
And, as expected, Republicans moved quickly to blame President Obama.
"Today's news is another sad reminder of President Obama's broken promise to cut the deficit in half," said House Speaker John Boehner, R-Ohio.
Ryan Williams, a spokesman for GOP presidential candidate Mitt Romney, said "the next generation has been saddled with enormous debt because of President Obama's policies."
A litany of congressional Republicans quickly put out similar statements after the news came from the Treasury Department.
President Obama has said Republicans have blocked a debt deal because they don't want to replenish government revenues with higher taxes on the wealthy.
Obama has also said the debt began exploding under predecessor George W. Bush.
The debt passed the $16 trillion mark just hours before the Democrats opened their convention in Charlotte.
Last week, the Republicans mounted a "debt clock" in their convention hall in Tampa.
