What we have seen the Russians do is attempt to manipulate public confidence on both sides. So we've seen them encourage people go to a protest on one side; we've seen them simultaneously encourage people to go to that same protest on the other side.

Border security is the most basic and necessary responsibility of a sovereign nation.

I do absolutely believe that the climate is changing. I'm not prepared to determine causation.

Kirstjen Nielsen

We need to do more to prevent radicalization, the inspiration of terrorism in this country.

I took an oath when I became secretary of homeland security to defend and support the Constitution.

What we have seen the Russians do is attempt to manipulate public confidence on both sides. So we've seen them encourage people go to a protest on one side; we've seen them simultaneously encourage people to go to that same protest on the other side.

It is my great honor to represent the men and women of DHS who work every day to enforce our laws and secure our nation.

Kirstjen Nielsen

We are a country based on the rule of law.

Kirstjen Nielsen

I would hate for anybody not to abide by alert warnings coming from government systems.

Kirstjen Nielsen

There is no need for a wall from sea to shining sea.

Kirstjen Nielsen

I think occasionally it's the presence - or increased presence - of federal law enforcement that can cause that fear.

Kirstjen Nielsen

By preventing the federal government from removing known criminal aliens, we allow our country to be a safe haven for criminals.

If you are a DACA that's compliant with your registration, meaning you haven't committed a crime, you, in fact, are registered, you're not priority of enforcement for ICE should the program end.

Kirstjen Nielsen

We need to fund our troops. We need to protect them. We need to increase homeland security. These are vital national security interest we need to fund.

Kirstjen Nielsen

We want to find a permanent solution to the DACA population, not a continual three-year renewal period.

Kirstjen Nielsen

Asylum is for people fleeing persecution, not those searching for a better job. Yet our broken system - with its debilitating court rulings, a crushing backlog, and gaping loopholes - allows illegal migrants to get into our country anyway and for whatever reason they want. This gaming of the system is unacceptable.

Kirstjen Nielsen

My decision has been that anyone who breaks the law will be prosecuted. If you're a parent or you're a single person or you happen to have a family, if you cross between the ports of entry, we will refer you for prosecution. You've broken U.S. law.

Kirstjen Nielsen

I do believe that Russia did and will continue to try and manipulate Americans' perspective on a whole variety of issues.

Kirstjen Nielsen

I fully intend in all cases and in all ways at all times to fully comply with all laws. I would expect the same of any employee or member of DHS.

Kirstjen Nielsen

People think of border security in very different ways, but to me, it's very simple: border security is national security.

Kirstjen Nielsen

What we've done as a country is, we've said we owe it to our citizens to know who is traveling here and if they intend to do us harm.
