McCarthy told The Hill in an interview for the weekly Power Politics podcast that he is unaware of any more sexual harassment claims against members of Congress, but he pledged more action in the future. The House on Wednesday passed a resolution mandating training to prevent harassment.

“It’s not something that we’re going to write a bill and walk away from. I think this should be a yearly review of the process. Do we have the best practices in place? And it’s something we should come back to every year and look,” McCarthy said. “There should be zero tolerance. I get upset when I read back finding out later of a settlement that people don’t know, of individuals who are serving here and their leadership defending them.”

McCarthy said he has already required his staff to undergo training, and that he himself has completed the training as well.

“You should not hide if there’s a payment. You should not tolerate it, in any place or form. If you are notified about it, you should make sure to investigate it. You can’t allow that activity to happen here in the House,” he said.

But outside watchdogs say Congress’s current system for dealing with harassment — a process that involves the Office of Compliance and perhaps the Ethics committees — remains unacceptably opaque.

“If they were to stop at training, no one will believe they have done their jobs,” said Fatima Goss Graves, president and CEO of the National Women’s Law Center. “If you have training without any sense that there will be real accountability, then it’s not going to make any sort of dent.”

McCarthy said harassment is not a partisan issue. Republicans and Democrats in state legislatures across the country have been accused, and in some cases resigned their positions after allegations of improper behavior.

“We’ve got to look and make sure we have the right protections here, that everybody’s protected. Remember, we are a microcosm of society, so anything good or bad that’s happening in society could be happening right here,” McCarthy said.

McCarthy said a part of a better training regimen includes acknowledging an evolving society, in which behavior that might once have been acceptable is no longer treated as such.

“It is a changing society. How we go about carrying out our work today is different because of social media. How people interact and the jokes they tell to one another, sometime in a different era may be viewed as okay and today it’s not. Are those individuals being trained and educated on what’s proper inside?” McCarthy said.

Goss Graves, of the National Women’s Law Center, called for reforms that would extend new transparency to the complaint and settlement process.

“The public needs to understand what it looks like as well. It cannot just be that entirely closed off process where no one knows anything about how they’re making decisions. They’re not going to inspire confidence,” Goss Graves said.
