Sen. Joe Manchin said he is not holding talks with top Democrats on the Build Back Better Act, a $1.75 trillion investment in social programs and climate policy.

Manchin, whose vote Democrats need to pass the bill, said last month that he would oppose it.

The senator, a conservative Democrat, has not closed the door on additional talks, and indicated that it may be “much easier” to reach an agreement on climate policy than on other provisions.
