The Congress should hold hearings into allegations of Navy sailors being subjected to extreme hazing, Rep. Joe Sestak (D-Pa.) said Monday.

Sestak, a retired Navy admiral, said during an appearance on CNN that the House Armed Services Committee (on which he serves) should look into alleged hazing incidents that went so far as to have reportedly driven a female sailor to suicide.

"Yes, it is," Sestak said on CNN when asked if it is appropriate for the Armed Services Committee to hold hearings, adding that it should be held by the personnel subcommittee.

The Pennsylvania lawmaker, who is running in the Democratic primary for Senate against incumbent Sen. Arlen Specter next year, characterized the hazing revelations as an isolated incident.

"This truly is an aberration," Sestak explained, though cautioning that ultimate responsibility for the hazing lies up the chain of command within the Navy.

"Look, we officers -- commissioned officers are ultimately the ones responsible," he said. "And that's why I want to know who actually, up the chain, knew about the accountability."
