If I need to record a telephone interview (and have permission to do so), I use a low-tech option: the Olympus TP-8 Telephone Pick-up Microphone, which works instantly and reliably on any phone I might have to use, land line or cellular.

Whenever I travel for work, I constantly take photos with my Pixel 2 cellphone that might seem like irrelevant details but that offer fact-checkable color in greater detail than I could ever write down in a notepad. They are then automatically backed up when I am on Wi-Fi by Google Photos.

Also: LastPass helps me securely manage the dozens of websites I have passwords for. LinkedIn is helpful, in finding people and getting biographical information, as is an extension called ContactOut, which helps find emails and other contact info for LinkedIn users. Signal has become an important tool to communicate with certain sources. Twitter is a huge distraction, but is also an essential tool to keep up to date on topics I am tracking, and to help promote the work of The Times.

One of your recent scoops involved uncovering the emails of Scott Pruitt, the head of the Environmental Protection Agency. You must pore through thousands of documents for these investigations. Do you use any special tools to stay organized or streamline the process?

One of the most challenging parts of my job is the massive number of documents I have to read, most of which are junk, but hidden in there are some real gems. A PDF reader is just not good enough.
