Charles Herbster, who chairs the president’s Agriculture and Rural Advisory Committee, spent $1.51m (£1.2m) on the world’s most expensive bull.
The Nebraska rancher and Republican donor splashed out on the prize Angus cattle at a record-breaking auction in North Dakota on Saturday.
Herbster Angus Farms bought from the bull – known as “SAV America 8018” – from breeders Schaff Angus Valley.
The sale smashed the previous record of $800,000, set by another Schaff Angus Valley bull last year.
Will Bollum, a reporter for livestock publication Western Ag Reporter who was present at Sunday’s action, told ABC: "The atmosphere was going crazy, you could feel the excitement in the air, even the auctioneer said it - he's never had to say numbers that are that high.
“So it was new for everybody, and it just a very unique experience, exciting for the buyer and the contending bidder all the way up to the $1m, $1.5m mark”
According the sales brochure, $1.51m buys you a beast “with true herd bull authority – long bodied, thick, square-hipped, deep and massive with a sound structure, large scrotal and gentle disposition.”
The animal's genetics and lucrative semen account for its unprecedented price.
The bull will remain at Schaff Angus Valley, which has retained a 20 per cent share of its semen as part of the sale.
