In a speech to the Bundestag lower house of parliament to open a debate on the 2013 German budget, Schaeuble said worries about U.S. debt were a burden for the global economy, hitting back at Washington which has criticized Europe for failing to get a grip on its own debt crisis.

In private, German officials often express concern about U.S. debt levels and the inability of politicians there to reach a consensus on how to reduce it, but Schaeuble’s public remarks underscore the extent of the worries in Germany.

“Ahead of the election in the United States there is great uncertainty about the course American politics will take in dealing the U.S. government’s debts, which are much too high,” Schaeuble said.
