CNN News:美国第115届国会将举行 多数席位面临改选

Taking you to Capitol Hill today, where things are starting to take shape after the November 8 election, when the 115th Congress convenes early next January, Paul Ryan, a Republican from Wisconsin, will remain speaker of the House of Representatives. He was reelected earlier this week to serve as second term in the position.
The job of House minority leader though was less certain. It's currently held by Nancy Pelosi, a Democrat from California. She's running to keep the job, but Ohio Democrat Tim Ryan announced yesterday he plans to challenge her for it.

In the Senate, Republicans reelected Kentucky Senator Mitch McConnell as majority leader. Democratic Senator Harry Reid from Nevada is the current minority, but he's retiring, and Senate Democrats chose Chuck Schumer from New York as the new Senate minority leader.
There will be a change in the president of the Senate, too. The U.S. vice president serves in this role, but doesn't get a vote unless senators are evenly divided 50-50. The president of the Senate can then cast the tie breaker. Right now, the job is held by Vice President Joe Biden. On January 20th, inauguration day, it will shift to Vice President-elect Mike Pence.
