United States President Donald Trump announced Tuesday his intent to nominate Neil Gorsuch to the Supreme Court. As the likely next justice on the high court, his nomination was likely to bring up questions about his background — including his net worth.

Gorsuch, 49, serves on the 10th circuit court of appeals in Colorado. He's the son of Anne Gorsuch Burford, who headed the Environmental Protection Agency in the 1980s before she resigned amid allegations that she mishandled toxic waste cleanups. With degrees from Columbia University and Harvard Law School, Gorsuch was nominated and confirmed for his most recent position by President George W. Bush in 2006, according to SCOTUS Blog.

Gorsuch's 2015 financial disclosure report showed he received $26,000 for teaching at the University of Colorado Law School and about $5,300 in book royalties. His investments, represented only as ranges in the report, could add up to $7.2 million, according to He has financial holdings with the United States Automobile Association and municipal bonds, according to the National Law Journal.

Supreme Court associate justices make $249,300 yearly, while the chief justice earns $260,700, according to the National Taxpayers Union Foundation. This is up from a decade ago, when associate justices made $203,000 and their leader made $212,100.

It's hard to figure out justices' exact net worth because financial disclosure forms only require them to list investments in ranges.

As of 2013, Ruth Bader Ginsburg had likely the highest net worth on the Supreme Court, with between $4.4 million and $18.1 million in income and assets, according to the Center for Public Integrity. Just behind her was Stephen Breyer, whose net worth was estimated between $5 million and $17.1 million, and Sonia Sotomayor, whose assets were thought to total between $1.7 million and $10.3 million.

Justices in general enjoy lots of travel — the late Antonin Scalia went on 28 reimbursed trips in 2013 — and income from universities where they teach when they're not in session, CNN reported.
