John Kline's political slush fund
Such political action committees are largely unregulated and allow donors to make contributions of up to $5,000. Politicians then use the funds to ladle out cash to the campaigns of political allies.
Silverstein makes the case that the Freedom & Security PAC is substantially funded by companies who benefited from a Kline co-sponsored bill that reduced pension obligations for some businesses. Corporations such as Northwest Airlines and United Postal Service achieved significant savings through the 2006 legislation. According to federal filings, in August UPS spent $2,750 to throw a fundraiser for the Congressman's newly created slush fund. So far the PAC has raised roughly $43,000.
