Specifically, Weiner seems to be targeting Goldline, which is a regular sponsor of Beck’s TV show, radio program, and web properties.
A press release announcing the investigation states:
Goldline employs several conservative pundits to act as shills for its’ precious metal business, including Glenn Beck, Mike Huckabee, Laura Ingraham, and Fred Thompson. By drumming up public fears during financially uncertain times, conservative pundits are able to drive a false narrative…
Glenn Beck for example has dedicated entire segments of his program to explaining why the U.S. money supply is destined for hyperinflation with Barack Obama as president. He will often promote the purchase of gold as the only safe investment alternative for consumers who want to safeguard their livelihoods. When the show cuts to commercial break, viewers are treated to an advertisement from Goldline.
