The Post notes that USA Today was the first to report the campaign. From USA Today:
"Michael Bloomberg has declared war on the NRA and our 5 million members," Chris Cox, executive director of the NRA's Institute for Legislative Action, said in an e-mail. "We will not sit back and let him use his billions of dollars to impose his radical anti-freedom agenda on the American people."The NRA plans to spend $500,000 on the first round of ads which will run in several states including Colorado.
