Oh look, another witch hunt

The thing is: The Benghazi committee is not even the worst committee in the House. I'd argue that the House science committee, under the chairmanship of Lamar Smith (R-TX), deserves that superlative for its open-ended, Orwellian attempts to intimidate some of the nation's leading scientists and scientific institutions.

The science committee's modus operandi is similar to the Benghazi committee's — sweeping, catchall investigations, with no specific allegations of wrongdoing or clear rationale, searching through private documents for out-of-context bits and pieces to leak to the press, hoping to gain short-term political advantage — but it stands to do more lasting long-term damage.

In both cases, the investigations have continued long after all questions have been answered. (There were half a dozen probes into Benghazi before this one.) In both cases, the chair has drifted from inquiry to inquisition. But with Benghazi, the only threat is to the reputation of Hillary Clinton, who has the resources to defend herself. With the science committee, it is working scientists being intimidated, who often do not have the resources to defend themselves, and the threat is to the integrity of the scientific process in the US. It won't take much for scientists to get the message that research into politically contested topics is more hassle than it's worth.

This year, Smith was one of the committee chairs granted sweeping new subpoena powers by his fellow House Republicans, what one staffer called "exporting the Issa model." No longer is the chair required to consult with the ranking member before launching investigations or issuing subpoenas. A spokesperson for Nancy Pelosi (D-CA) said, "This change will inevitably [lead] to widespread abuses of power as Republicans infect the other committees with the poisonous process that Issa has so abused during his chairmanship."

That turned out to be pretty prescient, at least in the case of the science committee. No chair has taken to his new role with as much enthusiasm as Smith.
