This Will Not Pass: Trump, Biden, and the Battle for America's Future by Jonathan Martin and Alexander Burns:
There were bipartisan talks under way on a few subjects where lawmakers were trying to forge filibuster-proof compromises. In the Senate, the Connecticut Democrat Chris Murphy and the Texas Republican John Cornyn were holding quiet negotiations on gun regulation. A small group of Black lawmakers were trying to find a middle ground on police reform. Democrats has empowered Karen Bass in the House and Cory Booker in the Senate to lead bipartisan talks on policing legislation. On the Republican side, Mitch McConnell had promised Tim Scott of South Carolina, the Senate’s lone Black Republican, that if he could strike a deal, then the GOP leader would not obstruct passage.
But at the start of the spring none of those negotiations seemed on track for a quick breakthrough, and Democrats wanted to keep up the momentum they felt they’d achieved with the rescue plan.
