This does not surprise me.

Seeing as how many members of the Republican caucus, particularly House Minority Leader Kevin McCarthy, are hip deep in the conspiracies behind the January 6 insurrection, it comes as no surprise that House Republican leaders aggressively whipped the vote against a commission to investigate the matter.

This is why the idea of a bipartisan commission is a bad thing; unlike 911, Republican Representatives and Senators are suspects, and not just observers: 

The House of Representatives has voted in favor of a bill that would create a 9/11-style commission to investigate the deadly attack on the Capitol in January.

The vote fell largely along party lines, with 35 Republicans joining Democrats in passing the measure. However, 175 Republicans voted against the bill, as Republican leaders endeavored to put the deadly 6 January attack behind them, and reframe the riot as a protest.

………

“It sounds like they are afraid of the truth, and that’s most unfortunate, but hopefully they’ll get used to the idea that the American people want us to find the truth,” Nancy Pelosi, the House speaker, said as she sharply criticized Republicans for opposing the bill.

Three Republicans spoke in favor of the legislation: John Katko, Fred Upton and Peter Meijer. All were among the 10 who had voted days after the attack to impeach Trump for encouraging his supporters to attack the Capitol.

The Republican Party is an enemy of the Republic.
