WASHINGTON (AP) - A Tennessee lawyer who is the mysterious source of millions of dollars in contributions that were steered to national political candidates doubled his investments before Election Day and funneled an additional $6.8 million to a prominent Tea Party group.
William Rose of Knoxville says he's not obligated to disclose the origin of more than $12 million he routed through two nascent companies he owns.
The money went to the FreedomWorks for America "super" political committee, which spent it on high-profile congressional races. Rose made the latest contributions even as news organizations were investigating suspicious donations traced to him during October.
The contributions are emblematic of the murky world of who gives money to politicians after new federal rules allowing unlimited and anonymous donations.
