Republicans continue to criticize NPR and its CEO for political bias scandal.

Republicans in Congress are putting pressure on National Public Broadcasting (NPR) and the Corporation for Public Broadcasting (CPB) in response to NPR’s bias scandal. A series of letters has been sent to both organizations from House and Senate Republicans, asking for action to uphold NPR’s integrity and address allegations of ideological bias made by former senior editor Uri Berliner, who has since left NPR.

The House Committee on Energy and Commerce has requested NPR CEO Katherine Maher to appear for an Oversight and Investigations Subcommittee hearing on the allegations. Committee Chairwoman Cathy McMorris Rodgers, R-Wash., expressed concerns about the direction NPR may be heading under past and present leadership.

A group of Republican senators also sent a letter to Maher, urging her to address the ideological approach at NPR. NPR has offered to testify on a date that works for the committee, as Maher has a previously scheduled board of directors meeting. She will provide written testimony in her absence.

Senator Ted Cruz, ranking member of the Senate Commerce committee, sent a letter to CPB seeking answers in response to the scandal. The CPB spokesperson expressed anticipation for Maher’s responses to the committee’s letter.

Senate Committee on Commerce, Science, and Transportation Chairwoman Maria Cantwell, D-Wash., did not comment on the allegations against NPR or indicate whether Maher would testify in the Senate. Cantwell’s focus is on passing a five-year reauthorization, referencing the FAA reauthorization bill with a deadline of May 10.

Cruz and Senator Rick Scott, R-Fla., have both written letters to CPB scrutinizing grant funding to NPR in light of the scandal. The allegations of ideological bias at NPR have prompted discussions and bills in both chambers to reduce funding for the organization.

One such bill introduced by House Freedom Caucus Chair Bob Good, R-Va., aims to cut NPR’s federal funding and prevent public radio stations with federal grants from using them to purchase content from or pay dues to NPR. Berliner’s essay highlighting concerns with NPR, including a lack of Republican representation in the Washington D.C. newsroom, was published on April 9.
