Collins 'optimistic' Jan. 6 commission can pass Senate with modifications

Sen. Susan CollinsSusan Margaret CollinsTransit funding, broadband holding up infrastructure deal The Hill's Morning Report - Infrastructure vote fails; partisan feud erupts over Jan. 6 panel Senate falling behind on infrastructure MORE (R-Maine) on Sunday said she was "optimistic" Democrats and Republicans could reach a compromise on a bill to establish an independent commission to investigate the Jan. 6 attack on the U.S. Capitol but that changes needed to be made to the House-passed legislation.

"I'm optimistic that we can get past these issues based on recent conversations I've had with the Speaker of the House and the House majority leader," she said.

Collins said she wants to see two changes to the bill that passed the House last week with support from all Democrats and 35 Republicans. The House-passed bill calls for Democrats and Republicans to appoint an equal number of members to the commission, but Collins wants that bipartisanship to extend to commission staff as well. Staff should be either jointly appointed by both parties or staffed in equal numbers by both sides, she said.

The Maine Republican also said that she would want a guarantee that the commission's work would conclude before the end of the year, a sign Republicans are worried the commission could be used by Democrats to politically damage their foes should the probe stretch into 2022.

"I strongly support the creation of an independent commission. I believe there are many unanswered questions about the attacks on the Capitol on Jan. 6," Collins, one of seven GOP senators who voted to convict former President TrumpDonald TrumpTrump hails Arizona Senate for audit at Phoenix rally, slams governor Arkansas governor says it's 'disappointing' vaccinations have become 'political' Watch live: Trump attends rally in Phoenix MORE in his impeachment trial, said.

Collins's comments come as some doubt remains as to whether Democrats could find the necessary 10 Republican defections required to pass the legislation, a prospect that grew less likely with McConnell's announcement of opposition last week.

"I've made the decision to oppose the House Democrats slanted and unbalanced proposal for another commission to study the events of Jan. 6," McConnell said Wednesday, adding that the decision came "after careful consideration."
