WASHINGTON — Sen. Kyrsten Sinema said Wednesday she doesn't support a $3.5 trillion price tag on a major spending bill that Democrats are trying to pass on a party-line basis, a position that will likely force the White House to scale back its ambitions.

"I have told Senate leadership and President Biden that I support many of the goals in this proposal to continue creating jobs, growing American competitiveness, and expanding economic opportunities for Arizonans. I have also made clear that while I will support beginning this process, I do not support a bill that costs $3.5 trillion," the Arizona Democrat said in a statement.

She added that "in the coming months, I will work in good faith to develop this legislation with my colleagues and the administration to strengthen Arizona's economy and help Arizona's everyday families get ahead."
