[379][380] After months of negotiations among Biden and lawmakers, in August 2021 the Senate passed a $1 trillion bipartisan infrastructure bill called the Infrastructure Investment and Jobs Act,[381][382] while the House, also in a bipartisan manner, approved that bill in early November 2021, covering infrastructure related to transport, utilities, and broadband.[383] Biden signed the bill into law in mid-November 2021.[384]
The other core part of the Build Back Better agenda was the Build Back Better Act, a $3.5 trillion social spending bill that expands the social safety net and includes major provisions on climate change.[385][386] The bill did not have Republican support, so Democrats attempted to pass it on a party-line vote through budget reconciliation, but struggled to win the support of Senator Joe Manchin, even as the price was lowered to $2.2 trillion.[387] After Manchin rejected the bill,[388] the Build Back Better Act's size was reduced and comprehensively reworked into the Inflation Reduction Act of 2022, covering deficit reduction, climate change, healthcare, and tax reform.
