(CNN) – Amid growing conservative outrage over National Public Radio's firing of journalist Juan Williams, South Carolina Sen. Jim DeMint is introducing a measure to strip the organization of government funding.
"Once again we find the only free speech liberals support is the speech with which they agree," said DeMint in a statement. "The incident with Mr. Williams shows that NPR is not concerned about providing the listening public with an honest debate of today's issues, but rather with promoting a one-sided liberal agenda."
NPR fired Williams after the liberal journalist told Fox News host Bill O'Reilly on Monday that he gets "worried" and "nervous" on flights when he sees people wearing "Muslim garb."
NPR says federal funding comprises less than 2 percent of its budget, with most of its financial support coming from station fees, sponsorships and grants.
"Since 2001, the Corporation for Public Broadcasting, which funds programming for National Public Radio and the Public Broadcasting Service, has received nearly $4 billion in taxpayer money," DeMint also said in the statement. "The country is over $13 trillion in debt and Congress must find ways to start trimming the federal budget to cut spending.
Several conservatives have called for NPR to be stripped of its funding, including former presidential candidate Mike Huckabee and former Alaska Gov. Sarah Palin.
