NEW YORK — Hope Hicks, a former top aide to Donald Trump, appeared to break down crying on the witness stand Friday at Trump’s criminal trial, where she described campaign and White House efforts to keep a lid on scandalous stories about his past sex life.

Her time on the stand marked a significant shift in the focus of trial testimony; after days of hearing about tabloid editors and secret deals to stifle or sell celebrity gossip, the jury was led through the whirlwind of the 2016 presidential campaign and directly to the Oval Office.
