Nuke chief Jaczko: I won’t resign

The concerns came to light late last week when Committee Chairman Darrell Issa (R-Calif.) released a mid-October letter from the commissioners to the White House arguing that Jaczko’s behavior is causing “serious damage” to the agency.

Several Republicans have called for Jaczko’s ouster in recent days, citing the commissioners’ concerns about his leadership.
