WASHINGTON (AP) \u2014 President Joe Biden said his infrastructure and families agenda must be passed to sustain the economic momentum of his first six months in office, aiming to set the tone for a crucial week of congressional negotiations on the two bills.\r\n\r\nBut\u00a0<a href="https:\/\/apnews.com\/article\/joe-biden-business-government-and-politics-climate-change-3172b459fd33c92eb3b1e648e3e98437">a Wednesday deadline set by Senate Majority Leader Chuck Schumer<\/a>\u00a0on the bipartisan infrastructure bill was in doubt as Republicans signaled they would block a procedural vote, for now, while details are still being worked out. Senators are wrangling over how to pay for the new spending in the $1 trillion package of highway, water system and other public works projects.\r\n\r\nAt the same time, Democrats are developing the particulars of a separate bill that would invest\u00a0<a href="https:\/\/apnews.com\/article\/joe-biden-business-government-and-politics-personal-taxes-c80b07740f63853c78d41d900b265ed2">a stunning $3.5 trillion<\/a>\u00a0nationwide across Americans' lives \u2014 with support for families, education, climate resiliency and other priorities that they aim to ultimately pass with solely Democratic support. Democrats hope to show progress on that bill before lawmakers leave Washington for their recess in August.\r\n\r\nThe legislative maneuvering marks a major test of Biden\u2019s ability to deliver on a massive package of economic promises and reforms he made during his campaign. He\u2019s been putting public pressure on lawmakers with a series of speeches highlighting the strengthening economy while emphasizing the need for further investment to continue that growth and to bolster the middle class. Biden's top aides met with senators late Monday.\r\n\r\n\u201cWhat the best companies do \u2014 and what we as a country should do \u2014 is make smart, sustainable investments with appropriate financing," the president said Monday at the White House.\r\n\r\nCalling his plans a \u201cblue-collar blueprint for building an American economy back,\u201d Biden said, \u201cThis is the best strategy to create millions of jobs and lift up middle class families, grow wages and keep prices affordable for the long term.\u201d\r\n\r\nThe economy has come back to life as more Americans have gotten vaccinated and\u00a0<a href="https:\/\/apnews.com\/article\/house-vote-coronavirus-relief-package-33f4902ca9a2aed4e76274af6bb2ea5c">Biden's earlier $1.9 trillion relief package<\/a>\u00a0has coursed through the country. Employers have added an average of nearly 543,000 jobs a month since January, with Federal Reserve officials anticipating overall economic growth of roughly 7% this year that would be the highest since 1984. Yet there is also uncertainty as employers say they're struggling to find workers at the current pay levels and inflation concerns have yet to fully abate.\r\n\r\nSenate Republican leader Mitch McConnell decried the \u201cspending spree\u201d as \u201cthe last thing American families need.\u201d\r\n\r\nMcConnell and outside groups including the conservative Americans for Prosperity encouraged Republicans to vote against proceeding to the bipartisan package until they have more details. \u201cI think we need to see the bill before we decide whether or not to vote for it,\u201d McConnell told reporters at the Capitol.\r\n\r\nThe president is pushing for more than $4 trillion in combined spending with the hopes of prolonging solid economic gains. Biden\u2019s $3.5 trillion package focused on climate, schools and families will need support from all 50 Senate Democrats to clear a party line vote.\r\n\r\nKey to Biden\u2019s message is that the growth is occurring as intended and helping the U.S. middle class. Yet much of it is expected to fade as the economy fully heals from the pandemic.\r\n\r\nBut\u00a0<a href="https:\/\/apnews.com\/article\/joe-biden-wi-state-wire-business-1128a8b10e8c67264231f91d47652ade">the $973 billion infrastructure deal<\/a>\u00a0Biden struck with a group of Republican and Democratic senators lacks a clear plan for how to pay for it as GOP lawmakers have backed away from tax compliance enforcement by the IRS.\r\n\r\nInstead, senators in the bipartisan group are considering rolling back\u00a0<a href="https:\/\/apnews.com\/article\/donald-trump-medication-prescription-drug-costs-medicare-prescription-drugs-e171198402445755b920842ded293b59">a Trump-era rule on pharmaceutical rebates<\/a>\u00a0that could bring in some $170 billion to be used for infrastructure. No decisions have yet been made as senators huddled late Monday with administration officials on next steps.\r\n\r\nSen. Rob Portman of Ohio, a chief Republican negotiator, said they resolved half of the estimated two dozen unresolved issues after a marathon round of talks late Sunday with the White House.\r\n\r\n\u201cIt\u2019s absurd to move forward with a vote on something that is not yet formulated,\u201d he said.\r\n\r\nOver the weekend Republicans chafed at the prospect of a Wednesday vote, noting that major questions over how to pay for the spending still remain unanswered. The package needs 60 votes to defeat\u00a0<a href="https:\/\/apnews.com\/article\/joe-biden-politics-filibusters-f476940e279b6bc2a1bbfd7c5cc24f96">a GOP filibuster<\/a>, a delaying tactic, and pass the Senate \u2014 which means at least 10 Republicans have to join all 50 Democrats in supporting it. With Republicans still expressing concerns over the package, the success of the Wednesday procedural vote remains in doubt.\r\n\r\n\u201cIt\u2019s time to begin the debate,\u201d Schumer said Monday, setting up the votes.\r\n\r\nSen. Jon Tester of Montana, a key Democratic negotiator, said if Republicans block the vote with a filibuster \u201cthat\u2019s a problem. Hopefully, people will be smarter than that.\u201d\r\n\r\nWhite House press secretary Jen Psaki dismissed questions Monday over the future of the bill and what the administration would do if Wednesday's vote is unsuccessful.\r\n\r\n\u201cTwo days is a lifetime in Washington, so I don\u2019t think we\u2019re going to make predictions of the death of the infrastructure package,\u201d she told reporters.\r\n\r\nBiden also used his Monday remarks to push back against Republican critics of his plans who argue massive federal investments in the economy will accelerate inflation.\r\n\r\n<a href="https:\/\/apnews.com\/article\/business-prices-consumer-prices-7c0dceffdbd50a8b1b888af5d3b922ed">Consumer prices climbed 5.4% for the year<\/a>\u00a0that ended in June, the highest annual increase since August 2008. Higher inflation can erode the wages of workers and ultimately hurt economic growth.\r\n\r\nBiden said Monday that his proposed investments would help rebuild U.S. supply chains and ease pressures on U.S. production that some economists say have contributed to inflation.\r\n\r\n\u201cIf we make prudent, multi-year investments in better roads, bridges, transit systems and high speed internet, a modern resilient electric grid, here\u2019s what will happen: It breaks up the bottlenecks in our economy,\u201d he said.\r\n\r\n\u201cThese steps will enhance our productivity, raising wages without raising prices. That won\u2019t increase inflation, it\u2019ll take the pressure off of inflation,\u201d Biden added.\r\n\r\n___\r\n\r\nAssociated Press writers Alan Fram, Lisa Mascaro and Kevin Freking contributed to this report.
