According to Odaily, U.S. Trade Representative Jamieson Greer is set to testify before the Senate Finance Committee on Tuesday. Greer is responsible for implementing the global tariffs announced by U.S. President Donald Trump last week. This marks the first congressional testimony by a Trump administration official since the tariffs were declared.

Lawmakers are expected to question Greer about the scope and duration of Trump's tariff plan, as both Republican and Democratic members have expressed concerns. There is growing apprehension among Republicans in Congress regarding the tariffs' impact on the U.S. stock market and global trade relations with allies.

At least seven Republican senators have backed a bill to prevent Trump from imposing tariffs unilaterally. However, senior Republican leaders have indicated that the Senate will not consider the legislation following Trump's veto threat issued on Monday.
