The Trump administration on Monday asked a U.S. appeals court to pause a second court ruling that found the president had exceeded his authority by imposing sweeping tariffs on imports, saying the decision jeopardizes trade negotiations with other nations.

The president is set to raise tariffs on steel and aluminum this week, even as the courts are challenging the legitimacy of other levies.

The Trump administration has asked a federal appeals court to block an order last week that found the president's sweeping tariffs were "unlawful."
