Friday is a big day on Capitol Hill.

The 119th Congress will be sworn in, a top leader will fight to keep his post, and Georgia Democratic Sen. Raphael Warnock will get one of the biggest committee positions he has ever had.

He is now on the Finance Committee, which is expected to be ground zero for funding battles over Social Security, Medicare, Medicaid and the Affordable Care Act.

Warnock will also have a vote on tariffs and taxation, two big issues for incoming President Trump.
