Senior House lawmakers are battling over the contours of a panel inspired by the 9/11 Commission to investigate the deadly Capitol insurrection on Jan. 6, with Republicans demanding equal representation. Speaker Nancy Pelosi and her Republican counterparts have already traded one offer each but still remain at odds over several issues including membership on the proposed commission, according to multiple sources familiar with the talks. Pelosi, who's vowed to quickly take up legislation creating the commission, proposed tilting the panel in favor of Democrats, with her party getting to pick seven of the members while Republican leaders choose four additional appointees. But Republicans are insisting on an equal split " each party gets to appoint five members " in their counteroffer, sources told POLITICO.
