Just go read this story about how one of Tom DeLay's friends got Texas Congressman Sam Johnson to instigate a complaint against Texans for Public Justice with the IRS for its role in exposing DeLay's financial shenanigans. As Josh Marshall puts it:
DeLay fundraising lawyer is worried that TPJ might end up deep-sixing the boss. DeLay fundraising lawyer contacts DeLay-lackey congressman and asks him to sic the IRS on TPJ. DeLay-lackey congressman does as he's told. And so does the IRS. TPJ gets put the wringer for uncovering information about DeLay's crimes.
