"No, I think we are prohibited from under the law - in terms of the strict confidentiality that adheres to each one of our processes, and the non-disclosure agreements, we cannot disclose who they are," Grundmann added.
Grundmann said new reporting standards approved by the House would reveal every six months which offices had some type of legal settlements - and she also said that if a lawmaker agreed to a workplace settlement, taxpayers would pay the bill up front - and then have that member of Congress reimburse Uncle Sam within 90 days.
So far, the House and Senate have not finalized an agreement on legislation to set new standards for transparency on workplace settlements involving lawmaker offices, as one leading Democrat today again demanded action by both chambers.
"The Senate has no more excuses," said Sen. Kirsten Gillibrand (D-NY).
Back in Wednesday's House hearing, lawmakers did not like to hear that while reforms in the House would publicly name the lawmaker and/or a top staffer if they were involved in harassment of other staffers, a Senate reform plan would not be as sweeping.
"So, if a Chief of Staff engages in that conduct, or anyone else that isn't the member, then their conduct is not disclosed?" Wasserman Schultz asked.
"That's correct," replied Grundmann.
"That's absolutely unacceptable," the Florida Democrat said.
The hearing came days after the resignation of Rep. Blake Farenthold (R-TX), who had taxpayers foot the bill for an $84,000 settlement with a former office employee - Farenthold had promised to pay that money, but now that he is gone, it seems unlikely to happen.
Meanwhile, Grundmann denied press reports in recent weeks that any personal information about sexual harassment or workplace abuses in Congressional offices was left on unsecured computer servers.
"We have not been hacked. We have never stored our data on an unsecured server," as Grundmann said their computer precautions had been described by officials as "Fort Knox."
"Fort Knox doesn't talk about their cyber security," she added, offering to brief members in private about the issue
