Trump administration launched online portal on Monday after supreme court struck down tariff policy earlier this year

Hello and welcome to the US politics live blog.

The Trump administration is expected to launch a refund system for businesses that paid tariffs later struck down by the supreme court. It is the first step in paying back $166bn in tariffs after justices ruled the Trump administration was overstepping its constitutional powers.

Importers and their brokers will be able to begin claiming refunds through an online portal beginning at 8 am ET, according to US Customs and Border Protection, the agency administering the system.

It’s the first step in a complicated process that also might eventually lead to refunds for consumers who were billed for some or all of the tariffs on products shipped to them from outside the United States, the Associated Press reports.
