But while the nonprofit, nonpartisan lobby group says it represents the interests of small business owners, some Democrats are raising questions about both its funding sources and its tax status.
The Congressional Progressive Caucus recently wrote a letter to NFIB questioning the group's motives and noting the lobby's ties to "corporate-funded activist groups," the Wall Street Journal reports. In 2010--the same year that NFIB joined the lawsuit against the health care law--the organization received $3.7 million from Crossroads GPS, a Republican campaign fund co-founded by former George Bush presidential aide Karl Rove, according to the Journal.
And the office of Rep. Raul M. Grijalva (D-Arizona) sent a letter to the Internal Revenue Service questioning NFIB's tax-exempt status, the Washington Post notes.
At press time, NFIB had not responded to a request for comment.
On Sunday, a Journaleditorial defended NFIB, saying that many small business owners oppose "ObamaCare" and the tax burden it places on companies. The Journal called recent criticism of NFIB was a "smear campaign" and an example of "liberal intimidation."
