川普争议性教育部长人选宣誓就任

U.S. Vice President Mike Pence swore in Betsy DeVos as U.S. secretary of education on Tuesday after casting the tie-breaking Senate vote to confirm President Donald Trump's controversial nominee. It was the first time in American history that a vice president had been needed to get a Cabinet pick approved.

DeVos pledged at her swearing-in to "support and defend the United States against all enemies, foreign and domestic." In the words of her official vow, she also pledged to "well and faithfully" discharge the duties of her office.

The ceremony took place quickly and without fanfare, except for the whirring and clicking of cameras and other media equipment. After the short ceremony was over, a small audience of family and friends burst into polite applause.

Earlier in the day, two Republicans voted with a united Democratic caucus in opposition to DeVos. The result was a 50-50 split before Pence cast the deciding vote, as the Constitution mandates when the chamber is evenly divided.
