Koch brothers won’t say whom they voted for

Charles and David Koch, the billionaire brothers who helm a major conservative donor network, aren’t saying who they voted for in the presidential race, according to CNN.

The Koch brothers have declined to spend any money on GOP presidential nominee Donald Trump and wouldn’t give any indication on Tuesday about whether they ended up backing him or his Democratic opponent, Hillary Clinton.

The Koch brothers had been under pressure by other big Republican donors to help Trump, but they have stood firm, citing policy differences with the nominee.

Their donor network has instead contributed tens of millions to down-ballot races to boost Republican incumbents and candidates and help protect the party’s slim Senate majority.
