A partner at the boutique firm Harris, Wiltshire & Grannis in Washington, D.C., reported earning more than $700,000 in compensation for legal services provided to clients including U.S. law firms, major U.S. technology companies and a bevy of energy and power outfits, according to a financial disclosure released Tuesday as part of his nomination to a key post in the Biden administration.

Samuel Walsh was nominated in April to serve as general counsel to the U.S. Department of Energy, and his return to the department would mark a sort of homecoming. Walsh worked for six years at the Obama-era energy department, where his roles included deputy general counsel for energy policy, associate general counsel and senior legal adviser to the general counsel.

Many top-level U.S. executive branch officials are required to disclose financial information about sources of income, and these public-record disclosures can provide a glimpse at compensation and clients at law firms small and large. Walsh's nomination is pending before the Senate Committee on Energy and Natural Resources.
