The Oracle of Omaha is investing once again in Nebraska's Democratic nominee for governor.
Warren Buffett, the Berkshire Hathaway chairman and the world's third-richest person, made another $100,000 campaign contribution to Chuck Hassebrook, said the candidate's spokeswoman, Meg Mandy. The news came as Hassebrook announced raising a total of $1.4 million from June 18 to Sept. 30.
Buffett's latest donation, which will be detailed in disclosure reports, matches the $100,000 he gave Hassebrook in June. In Nebraska, there's no limit on how much an individual can give to a candidate, according to the National Conference of State Legislatures.
Buffett has a net worth of $68.2 billion, according to the Bloomberg Billionaires Index. Buffett's daughter Susan is an honorary campaign co-chair of Hassebrook's campaign.
Hassebrook is running against Republican Pete Ricketts, who's also of billionaire stock: his father, Joe Ricketts, founded TD Ameritrade and created the Ending Spending Action Fund, a political organization he runs with his youngest son, Todd. Republican Dave Heineman is leaving office in January because of term limits.
