After a stint as media editor for the site Kos every dayBoehlert launched Press Run in 2020, which he described as “an unfiltered, impassioned and proudly progressive critique of the political press in the age of Trump.”

Ms Breslin said Mr Boehlert was an avid athlete and cyclist.

“Eric was brilliant and funny and kind,” she said. “He was an incredible father to Jane and Ben, present their whole lives.” Their daughter, Jane Boehlert, remembered him as “a wonderful father, an incredible person.”

“We miss him deeply already,” she said.

In Mr. Boehlert’s final Press Run article, published the day of his death, he questioned media coverage of the Biden administration, saying the media downplayed the president’s accomplishments.

“The glaring disconnect between reality and how the press portrays White House accomplishments means that a key question persists: Why is the press rooting against Biden?”

A statement from Mr. Boehlert’s family, provided to The New York Times by Richard Abate, Mr. Boehlert’s literary agent, describes him as “a fierce defender of democracy, social justice and truth in the media “.

“He was fearless and brilliant in his investigation of hypocrisies and double standards in the media, and his contribution was invaluable,” the family said. “Eric was full of enthusiasm and interest in life as a loving husband, father, brother, uncle and friend.”

Mr Abate said they had been friends for 45 years, having met in eighth grade. “He was the kindest, sweetest, warmest, most loving person I’ve ever known, and at the same time, he was an absolutely fierce warrior when it came to fighting injustice” , did he declare.
