Fox News, the Associated Press, the New York Times and the Washington Post have also corroborated various parts of The Atlantic’s reporting.
“For the first time in American history, a president has repeatedly shown utter and vulgar contempt and disrespect for those who have served and died serving our country,” Sullenberger wrote on Facebook.
“While I am not surprised, I am disgusted by the current occupant of the Oval Office. He has repeatedly and consistently shown himself to be completely unfit for and to have no respect for the office he holds,” he added.
Sullenberger, a retired Air Force fighter pilot, wrote that he and his father volunteered for military service in wartime and “that serving a cause greater than oneself is the highest calling, whether in the military or in civilian life.”
Sullenberger has always “tried to be a voice of reason and to speak in a measured way,” but he felt that he had to call out the President’s behavior, he wrote. Trump has “completely failed” to uphold his oath of office and “he has admitted that he cannot comprehend the concept of service above self,” the pilot wrote.
“He cannot understand selflessness because he is selfish. He cannot conceive of courage because he is a coward. He cannot feel duty because he is disloyal,” Sullenberger wrote.
