The top Republican in the House of Representatives has come out against a bipartisan commission to investigate the Jan. 6 riot at the Capitol because the commission wouldnt blame Black Lives Matter for the attack.

House Minority Leader Kevin McCarthy (R-Calif.) said in a statement Tuesday that the proposed commission ignores the political violence that has struck American cities and that it has a shortsighted scope that does not examine interrelated forms of political violence in America.

The House is set to vote this week on legislation establishing the commission. The bipartisan bill, negotiated by House Homeland Security Committee Chair Bennie Thompson (D-Miss.) and ranking member John Katko (R-N.Y.), is modeled on the bipartisan commission that investigated the terrorist attacks of Sept. 11, 2001.

The problem for McCarthy is that the Republican Party is thoroughly implicated in the Capitol riot, which former President Donald Trump incited with lies about the 2020 presidential election lies that McCarthy and most other congressional Republicans supported.

McCarthy and Senate Minority Leader Mitch McConnell (R-Ky.) initially resisted a commission proposal from House Speaker Nancy Pelosi (D-Calif.) because it would have had more Democratic than Republican appointees, but Pelosi conceded to an even party split weeks ago.
