FISA is a powerful tool - and we've got to be sure we're using it properly, at every step in the process. But we couldn't do our jobs without it.

All too often, vital electronic evidence has been made unavailable through encryption that doesn't allow for execution of legal process including court-approved search warrants.

Technology has made life much easier for the good guy - there's no doubt.

Cybersecurity is a central part of the FBI's mission. It's one part of the broader safety net we try to provide the American people: not only safe data, safe personal information, but also safe communities, safe schools.

We've got to make sure tech companies - all of them - aren't taking steps that will place content beyond the reach of the courts.

In this country, we value our open, free-market system - including the way it attracts international investment and talent to our country.

Understanding the Chinese counterintelligence threat better will help us respond to it more effectively. China is taking a multi-faceted approach, so we've got to have a multi-faceted response.

Our folks at the FBI and at DOJ are working their tails off every day to protect our nation's companies, our universities, our computer networks, and our ideas and innovation.

China has national security laws that compel Chinese companies to provide the government with information and access at their government's request. And virtually all Chinese companies of any size are required to have Communist Party 'cells' inside them, to make sure the companies stay in line with the party's principles and policies.

We've created these Protected Voices videos to showcase the methods these adversaries might use, and to help campaigns practice good cyber hygiene, because the foundation of election security is cybersecurity.

Protected Voices aims to help political campaigns, private companies, and individuals protect themselves from foreign actors who want to hijack their message.

Your voice matters, so protect it.

All American voices are important, and the FBI's Protected Voices videos and resources will help all Americans protect themselves online.

The work of the FBI, to put it mildly, is complex and covers just about every threat we face.

What was once a comparatively minor threat - people hacking for fun or for bragging rights - has turned into full-blown economic espionage and extremely lucrative cyber crime.

9/11 was a gamechanger in so many terrible ways, not just for the United States and for our own national security apparatus but for the whole world. And those attacks blew apart any notion of separation between foreign and domestic threats, any notion that such attacks only happen to other people in other countries.

Criminal and terrorist threats are morphing beyond traditional actors and tactics. We still have to worry about things like an al-Qaida cell plotting a large-scale attack, but we also now have to worry increasingly about homegrown violent extremists radicalizing in the shadows.

China has pioneered a societal approach to stealing innovation in any way it can from a wide array of businesses, universities, and organizations.

Our folks at the FBI are working their tails off every day to stop and find criminals, terrorists, and nation-state adversaries.

Every time I attend an FBI graduation for new agents or new analysts at Quantico, a significant number of those graduates are former state and local officers, and I have the privilege of shaking their hands, presenting them with their credentials, and welcoming them to the FBI family.

It takes an incredibly special person to be willing to put his or her life on the line for a complete stranger. And to get up every morning, day after day after day, to do that, I think, is extraordinary.

A line of duty death, whether an officer, special agent, or professional staff employee, is personal to the FBI, and it's personal to me as Director.

It is the honor of a lifetime to serve as Director. I long ago grew to know and admire the FBI from my earliest days as a line prosecutor to my years as assistant attorney general.

As the Director of the FBI, I am committed to ensuring that the Bureau is being transparent and responsive to legitimate congressional requests.

The FBI's mission is to protect the American people and uphold the Constitution. To carry out that mission, we're entrusted with a lot of authority, so our actions are subject to close oversight - from the courts, from our elected leaders, and from independent entities like the inspector general.

We need to hold ourselves accountable for the work we do and the choices we make.

Technology companies have a front-line responsibility to secure their own networks, products, and platforms.

There's a clear distinction between activities that threaten the security and integrity of our election systems, and the broader threat from influence operations designed to influence voters.

Our adversaries are trying to undermine our country on a persistent and regular basis, whether it's election season or not.

Healthy competition is good for the global economy. Criminal conduct is not. Rampant theft is not. Cheating is not.

The Chinese government's not pulling any punches. They want what we have so they can get the upper hand on us. And they're highly strategic in their approach - they're playing the long game.

It's going to take all of us working together to protect our economic security and our way of life. The American people expect and deserve no less.

In pursuit of their commercial ambitions, Huawei relied on dishonest business practices that contradict the economic principles that have allowed American companies and the United States to thrive.

The prosperity that drives our economic security is inherently linked to our national security. And the immense influence that the Chinese government holds over Chinese corporations like Huawei represents a threat to both.

As Americans, we should all be concerned by the potential for any company beholden to a foreign government - especially one that doesn't share our values - to burrow into the American telecommunications market.

Our adversaries - terrorists, foreign intelligence services, and criminals - take advantage of modern technology to hide their communications; recruit followers; and plan, conduct, and encourage espionage, cyber attacks, or terrorism to disperse information on different methods to attack the U.S. homeland and to facilitate other illegal activities.

Just as our adversaries evolve, so, too, must the FBI.

As the threat to harm the United States and U.S. interests evolves, we must adapt and confront these challenges, relying heavily on the strength of our federal, state, local, and international partnerships.

ISIS uses traditional media platforms as well as widespread social media campaigns to propagate its ideology. With the broad distribution of social media, terrorists can spot, assess, recruit, and radicalize vulnerable persons of all ages in the U.S. either to travel to foreign lands or to conduct an attack on the homeland.

The FBI assesses HVEs are the greatest terrorism threat to the homeland.

Terrorists in ungoverned spaces - both physical and cyber - readily disseminate propaganda and training materials to attract easily influenced individuals around the world to their cause. They motivate these individuals to act at home or encourage them to travel.

The threat from unmanned aircraft systems in the U.S. is steadily escalating.

The inability to access evidence or intelligence despite the lawful authority to do so significantly impacts the FBI's ability to identify, investigate, prosecute, or otherwise deter criminals, terrorists, and other offenders.

We must build toward the future so that we are prepared to deal with the threats we will face at home and abroad and understand how those threats may be connected.

The FBI is engaged in a myriad of efforts to combat cyber threats, from improving threat identification and information sharing inside and outside of the government to developing and retaining new talent, to examining the way we operate to disrupt and defeat these threats.

Cyber criminals often operate through online forums, selling illicit goods and services, including tools that lower the barrier to entry for aspiring criminals and that can be used to facilitate malicious cyber activity.

I left DOJ's leadership back in 2005. At the time, we were still building our national security capabilities in the wake of the 9/11 attacks. And we'd made a lot of progress.

If you think about the average person and their interaction with law enforcement, their whole perspective on who we are and what we stand for - our brand, if you will - might be defined by just one interaction or encounter, a traffic stop, a visit to a school, or a response to a call for help.

Every officer, every deputy, every agent we lose is one too many. It's a loss to our organizations, of course, it's a loss to our community, and most importantly, it's a devastating loss to the loved ones they leave behind.

I can tell you that there are lots of ways for people to express their views and their disagreements. For me, the idea of doing it through an anonymous op-ed is about the furthest thing from my mind.
