By David Lawder HOUSTON, Nov 4 (Reuters) - Democrats' resounding sweep to a majority in Congress gives them a big microphone and spotlight to scrutinize President Donald Trump's trade policies, but largely leaves them unable to override his veto on any vote to overturn his tariffs or rescind trade authorities,

The Supreme Court overturned Trump's attempt to levy tariffs under the International Emergency Economic Powers Act (IEEPA) back in February. That legislation allows the president to block transactions and freeze assets during an "unusual and extraordinary" international emergency, like the 1979 Iran hostage crisis.

Incoming presumptive House Speaker Hakeem Jeffries is planning a legislative blitz against President Trump during the first 100 hours of Democrats’ time back in power.

WASHINGTON (AP) — Senate Democratic leader Chuck Schumer is vowing that Democrats will not allow President Donald Trump to put “a right-winger” on the Supreme Court once they take power, raising the possibility that his party could block a presidential nominee if there is a vacancy in the next two years.

The levies as well as trade fighting with Canada are facing a test in the state, where voters appear skeptical of free trade but also of the president’s erratic approach.
