Press secretary Jen Psaki said President Biden had called Sen. Shelley Capito, R-W.Va., who led the negotiations, to thank her for her proposal and was awaiting more details.
"We are also continuing to explore other proposals that we hope will emerge," Psaki said. A group of bipartisan senators led by Sen. Joe Manchin, D-W.Va., and Mitt Romney, R-Utah, is putting together a backup infrastructure proposal should current talks fall through. Romney said that proposal is "not quite" $1 trillion.
"Sen. Capito told the president that her team would provide us with more details later today, and we look forward to getting that information," Psaki said. She argued that the plan "provides no substantial new funds" for veterans’ hospitals, clean energy jobs, building modern rail systems, repairing transit systems and removing lead pipes.
In a press gaggle, Psaki said the Republican proposal, originally $568 billion, had come up "significantly," which she found "encouraging," but the White House believes there are other areas that need to be funded.
"Lastly, we are concerned that the proposal on how to pay for the plan remains unclear: We are worried that major cuts in COVID relief funds could imperil pending aid to small businesses, restaurants and rural hospitals using this money to get back on their feet after the crush of the pandemic," Psaki concluded.
A group of Republicans countered Biden’s $1.7 trillion offer -- down from $2.25 trillion -- with a trimmed-down $928 billion plan. Instead of bankrolling the proposal by raising the top corporate tax rate from 21% to 28%, they suggested repurposing unused COVID relief funds.
The roadmap laid out by Republicans would set aside:
--$506 billion for roads and bridges
--$98 billion for public transit systems
--$46 billion for rails, including Amtrak
--$21 billion for safety, such as the Federal Motor Carrier Safety Administration, the National Highway Traffic Safety Administration and the Pipeline and Hazardous Materials Safety Administration
--$22 billion for ports and waterways
--$56 billion for airports
--$22 billion for western water storage
--$72 billion for water infrastructure
--$65 billion for broadband
--$20 billion for infrastructure financing
A source familiar with the Biden administration’s thinking told FOX Business that there is not $700 billion in unspent federal relief funds as Republicans have said, and the vast majority has been spent or allocated. The source said 95% of the $3 trillion passed before President Biden took office has been obligated or is for the Paycheck Protection Program, unemployment insurance or nutrition assistance.
"We think there are better ways to pay for it," Psaki said in the press gaggle following her statement.
But 24 states are ending federal unemployment enhancement early.
The White House feels the American Rescue Plan is working as intended and large swaths of it have already been spent on $1,400 cash payments, funding for state and local governments, and relief for families and small businesses.
But Republicans have noted much of the funding from the American Rescue Plan wouldn't even be spent in 2021. An estimate from the Congressional Budget Office found that $1.09 trillion of the $1.9 trillion American Rescue Plan would be spent this year, $477 billion would be spent in 2022 and the rest would be spent up through 2031.
