Outside groups fear that congressional Democrats could come up short on Biden’s social spending package. They are concerned that moderates in the House may end up buckling if the budget scores on the bill come back worse than anticipated. And there is residual anxiety that one of the two wavering Senate Democrats — Joe Manchin of West Virginia and Kyrsten Sinema of Arizona — could vote “no” over concerns about inflation and long-term debt.

The clearest solution to avoiding this, they argue, is more Biden…

White House officials contend that Biden and his team remain in close touch with the Hill, and their legislative affairs staff continues to push the social spending bill toward a vote. The White House said it is communicating regularly with a range of lawmakers including Manchin, but did not answer when asked whether Biden has spoken to the West Virginia senator or other moderates in recent days.

“There has been no kind of slowdown when it comes to our Hill outreach,” a White House official said.
