The New York Times Publisher A.G. Sulzberger said Monday that the White House is “extremely upset” about its coverage on President Joe Biden’s age but the newspaper will “continue to report fully and fairly.”

“We are going to continue to report fully and fairly, not just on Donald Trump but also on President Joe Biden,” Sulzberger said in an interview with The Reuters Institute for the Study of Journalism.

“He is a historically unpopular incumbent and the oldest man to ever hold this office. We’ve reported on both of those realities extensively, and the White House has been extremely upset about it.”
