After months of negotiations, a massive bipartisan infrastructure bill that promises significant investments in every pocket of the country is getting President Joe Biden's signature on Monday.
Biden will be joined by a bipartisan group as he signs the $1.2 trillion infrastructure bill into law at a White House ceremony -- marking a major victory for lawmakers from both parties who committed to working in a bipartisan way and even more so for Biden, who campaigned on a promise to work across the aisle.
"For too long, we've talked about having the best economy in the world. We've talked about asserting American leadership in the world with the best and safest roads, railways, ports, and airports. Here in Washington, we've heard countless speeches, promises, and white papers from the experts," Biden is expected to say, according to a White House excerpt of his remarks. "But today, we are finally getting it done. And my message to the American people is: America is moving again. And your life is going to change for the better."

President Joe Biden speaks about the bipartisan infrastructure bill in the State Dinning Room of the White House, Nov. 6, 2021, in Washington.
The infrastructure package, with $550 billion in new spending, will address the nation's core infrastructure needs including $110 billion for highways, roads and bridges, $66 billion for passenger rail, $65 billion in high-speed internet, $55 billion for water, $39 billion in public transit, $25 billion for airports, $7.5 billion for electric vehicle charging stations, and $17 billion for ports, among other areas.
The White House said the plan will create on average 1.5 million jobs per year over the next decade.

Yet, what Biden hopes will be a key moment in his presidency comes amid a new ABC News poll showing only 41% of Americans approve of Biden's job performance while 53% disapprove. His keystone policy initiatives are far more popular than he is, with 63% support for the infrastructure bill. Just 31% say he's keeping most of his major campaign promises, and 35% think he's accomplished much overall.
Several Republicans are expected to join Democrats at the White House for the South Lawn signing ceremony, including Sens. Bill Cassidy, R-La., Susan Collins, R-Maine, and Rob Portman, R-Ohio, along with GOP Reps. Tom Reed, R-N.Y., and Don Young, R-Alaska, according to a White House aide. Sen. Lisa Murkowski is also expected to attend, according to a source familiar, as well as GOP leaders at the state and local level.

Sen. Kyrsten Sinema, D-Ariz., a leader in negotiations, is expected to speak ahead of the president, as well as Vice President Kamala Harris, House Speaker Nancy Pelosi and Senate Majority Leader Chuck Schumer.
Senate Minority Leader Mitch McConnell, who has touted the bill in his home state of Kentucky as "good for the country," also said last week he has "other things I've got to do other than go to the signing ceremony."

In all, roughly 18% of congressional Republicans who voted for the popular legislation are attending the afternoon signing -- and the entire group faces extreme criticism, and in some cases, death threats, for supporting the infrastructure package -- blowback encouraged by former President Donald Trump.

White House Press Secretary Jen Psaki holds a news conference at the White House in Washington, D.C, Nov. 12, 2021.
Amid the criticism also fueled by rising inflation -- in the wake of the consumer price index hitting its highest increase in three decades -- White House press secretary Jen Psaki said on Friday that the $1 trillion infrastructure bill, along with the $1.75 trillion reconciliation package still pending in Congress, will offset inflation.
"I would note that everyone from the Federal Reserve to Wall Street agree with our assessment that inflation is already expected to substantially decelerate next year," Psaki said in a press briefing. "And economists across the board also agree that the president's economic agenda … will not add to inflationary pressure and will ease inflationary pressure over the long term."

The White House has announced that former lieutenant governor of Louisiana and former New Orleans Mayor Mitch Landrieu, who helped that city recover from Hurricane Katrina, will join the Biden administration as a senior advisor and oversee the implementation of the package. Biden will also sign an executive order on Monday creating a task force to implement the package into law, which will be co-chaired by Landrieu and National Economic Council Director Brian Deese.

Sen. Joe Manchin departs after a vote on Capitol Hill on Wednesday, Nov. 03, 2021, in Washington, D.C.
But Biden's plan to "Build Back Better" is not complete.
Congressional Democrats still need to pass his $1.75 trillion social spending framework they plan to move through reconciliation, a lengthy budget process that would not require Republican support since Democrats hold razor-thin majorities in both chambers. That plan includes universal pre-K, funding to limit child care costs, a one-year continuation of the child tax credit expanded earlier this year, and, at the insistence of progressives and with the Speaker's support, four weeks of paid family and medical leave.

Speaker of the House Nancy Pelosi speaks during a weekly news conference at the U.S. Capitol building on Nov. 4, 2021 in Washington, D.C. Speaker Pelosi was asked about how the Biden administration's Build Back Better agenda affected Tuesday's election.
Democrats, appearing to move ahead with a new rule vote, argue that both packages will pay for themselves and are waiting for scoring from the Congressional Budget Office, expected by Friday, they hope will make their case to Manchin and other moderate House Democrats.
In the end, it took 87 days following the passage of the bipartisan infrastructure bill in the Senate to get the spending approved in the House, as well as two visits to the Capitol by the president and dozens of meetings between the White House and representatives.
