U.S. President Joe Biden n Thursday announced he has agreed to a deal on infrastructure with a bipartisan group of senators after White House officials and senators had a breakthrough the night before in infrastructure negotiations.

A CNN report notes that both Republican and Democratic senators said Wednesday evening there was an agreement reached with White House officials and 10 senators on a bipartisan infrastructure deal. On Thursday afternoon, Biden said he had signed off on the agreement.

"To answer your direct question, we have a deal," he said.

Many details of the plan remain unclear. But the CNN report reports citing multiple sources that the total cost of the plan is $1.2 trillion over eight years, with $559 billion in new spending.

The proposal is significantly less than what Biden had put forward initially, which was a $2.25 trillion plan to rebuild the nation's infrastructure and shift to greener energy over the next eight years.

The agreed bipartisan proposal would would be approved through the typical legislative process, which means 60 votes would be needed to pass key procedural steps in a body divided 50-50 Democrats and Republicans.
