It started as a routine conference call. But at some point during the call, Representative Anthony D. Weiner became furious, convinced that his scheduler had not given him a crucial piece of information.
His scheduler, John J. Graff, who was in the next room, suddenly heard the congressman yelling at him through the wall.
Then, Mr. Graff recalled, Mr. Weiner started pounding his fists on his desk, kicked a chair and unleashed a string of expletives.
Two weeks later, Mr. Graff, a Navy veteran, became the latest of a sizable number of staff members who have resigned after an abbreviated stint with Mr. Weiner, a Democrat who represents parts of Brooklyn and Queens.
"I push people pretty hard," said Mr. Weiner, who acknowledged getting upset at Mr. Graff. "And there are, from time to time, staffers who don't take to it or just don't like being pushed that hard. But I really regretted him leaving. He was a marine. I'm like, 'How bad is this?' It's even worse than boot camp."
