This may be the year when Congress finally cracks down on the corrupt World Health Organization. The last straw may be not what WHO did, but what it didn’t do.

The House Committee on Science, Space, and Technology has been investigating the International Agency for Research on Cancer, a unit of the WHO, amid accusations that IARC holds secret proceedings and conducts shoddy research to reach politically-motivated conclusions. Chairman Lamar Smith, R-Texas, who has been threatening to withhold federal funding for IARC, twice asked IARC to testify at a hearing to explain itself. IARC refused to send an official to answer questions at a February 6 hearing. The agency has received more than $48 million in U.S. tax dollars via the National Institutes of Health, and the U.S. is the WHO’s largest donor.
