WASHINGTON, Sept 2 (Reuters) - U.S. President Donald

Trump on Tuesday said his administration will ask the Supreme

Court for an expedited ruling on tariffs that a U.S. appeals

court found illegal last week.

The court ruling on Friday threatens to undercut the

Republican president's use of the levies as a key economic

policy tool. The court allowed the tariffs to remain in place

through October 14 to give the Trump administration a chance to

file an appeal with the Supreme Court.

Trump told reporters in the Oval Office when asked about

the court ruling that his administration will seek an expedited

ruling as early as Wednesday "because we need an early

decision."

Trump's tariff policy is a central pillar of his

economic agenda and he credits it with taking in billions of

dollars for the U.S. government.

"It's a very important decision, and frankly, if they

make the wrong decision, it will be devastation for our

country," he said.

U.S. Treasury Secretary Scott Bessent on Monday

expressed confidence that the Supreme Court will uphold Trump's

use of a 1977 emergency powers law to impose sweeping tariffs on

most trading partners.
