Yes. So we're talking about computer programs. We're talking about new technology to help prevent this kind of incident and, of course, the new technology has to be protected by strong cybersecurity.

It seems that you'll have no regard for timeliness when it comes to implementing congressional mandates and recommendations from the NTSB, from the GAO, or the Inspector General's Office.

According to a 2016 GAO report, PHMSA has not implemented one-third of its mandates.

Why shouldn't the top of their agenda be, not to mention the top of Congress's agenda be, to implement this requirement as a matter of state regulation or state law?

They are looking to their state and Federal governments to step up and make sure that we implement the rules that we have.

We want to offer our deepest sympathies and condolences to the family of Leonel Rondon, the young man who died because of an explosion.

So what you're telling us is that there are models out there that could be used that could help prevent this kind of incident from occurring?

We are going to make the Merrimack Valley gas system safer than ever and we're going to be here working with you to meet these commitments.

What I would urge you all to do is when a recommendation, even if you haven't finished the complete review, seems like there's an obvious recommendation out there, that state legislators could act on immediately, get that recommendation…

We lost one precious life and we all know that several others were hospitalized or injured.

It's 2018 in the United States of America and nobody should be worried when they come home at night that their house is going to explode, nobody.

We have to not only get to the bottom of what happened but make sure that we take steps to ensure it never happens again.

can cause psychological trauma and induce long-term mental health risks for children.

Both are possible. Because we are the United States. We do hard things.

But we do not need to detain children or separate them from their families in order to be secure.

We have the capacity, in the United States of America, to control our borders without harming children.

The concept of justice does not lie just in technicalities. It lies in the way we treat people, and it lies in an observance of our core values.

We are very grateful for your public service. We are grateful to your families for sharing that service with you.
