That’s peanuts compared with what the Koch brothers will save. Just days after the House passed its version of the federal tax law slashing corporate tax rates, House Speaker Paul Ryan collected nearly $500,000 in campaign contributions from billionaire energy mogul Charles Koch and his wife, according to a recent campaign donor report. Koch and his brother David spent millions of dollars to get the tax law passed and are spending millions more in a public relations campaign in an attempt to boost support for the law, The Wall Street Journal reported. Koch Industries, one of the largest private corporations in the nation, operates refineries and manufactures a variety of products. The new tax law — which slices corporate tax rates from 35 percent to 21 percent, slashes estate taxes and includes a special deduction for oil and gas investors — is expected to save the Koch brothers and their businesses billions of dollars in taxes.
