After Trump drama, new Pence national security aide steps down

WASHINGTON (Reuters) - A new national security aide to U.S. Vice President Mike Pence stepped down on Sunday, only two days after being officially named to the job, after a behind-the-scenes White House argument hit the headlines, a White House official said.

The appointment of Jon Lerner to Pence's team was one of the more short-lived personnel moves in a White House known for turbulent staff turnover and infighting, and the first to envelope the vice president, who works hard to stay out of the drama.
