The Biden administration is not happy with how the New York Times is covering Joe Biden’s advanced age, publisher A.G. Sulzberger said Monday.

The Gray Lady is committed to covering both President Biden and Former president Donald Trump fairly, despite pushback from the White House, Sulzberger said in an interview with the Reuters Institute for the Study of Journalism.

“We are going to continue to report fully and fairly, not just on Donald Trump but also on President Joe Biden,” Sulzberger said.

“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,” he added.

A poll released by ABC and Ipsos on February 11, in the wake of special counsel Robert Hur’s damning report, found that 86 percent of Americans believe Biden, 81, is too old to serve effectively. A clear majority, 59 percent, believe Biden and Trump, 77, are too old to serve, and an additional 27 percent think only Biden is too old. The poll was conducted using a random sample of 528 national adults and the margin of error is 4.5 percent either way.

Biden’s age and memory problems were highlighted in special counsel Hur’s final report on his investigation into Biden’s retention of classified documents.

“Mr. Biden would likely present himself to a jury, as he did during our interview of him, as a sympathetic, well-meaning, elderly man with a poor memory,” Hur remarked in the report. He also described an instance when Joe Biden forget when he was vice president and another instance where he could not recall the exact year his late son Beau Biden passed away.

Hur found evidence Joe Biden willfully possessed classified documents, but declined to pursue criminal charges against the sitting president. He is set to testify about the investigation next month in a public hearing.

The New York Times opinion section published multiple scathing editorials on Biden’s mental faculties following Hur’s report. The Times‘ editorial board urged Biden to hold more unscripted interactions with the public and conduct regular news conferences in order to counter public perception of his advanced age.

An NBC News poll taken in late January before the release Hur’s report found 75 percent of Americans have concerns about Biden’s age, including over half of Democrats. The poll used a sample of 1,000 registered voters and its overall margin of error is plus-or-minus 3.1 percent.

White House spokesman Ian Sams wrote a letter on February 13th to the White House Correspondents Association demanding the media soften its coverage of the contents of Hur’s report. The WHCA rejected Sams’ “inappropriate” dictates and suggested the Biden administration reach out to specific members of the media with concerns.

President Biden held a primetime press conference on February 8th upon the release of Hur’s report to dispute Hur’s findings about his age. At one point during the press conference, Biden mixed up the presidents of Egypt and Mexico.
