The dispute centers on President Biden’s proposal to package new investments in roads, bridges and pipes with billions of dollars to help children and families. Republicans say Biden agreed earlier this month to seek what they describe as “social” spending as part of another legislative effort, only to have his top aides take the opposite approach during the latest round of talks Friday. “We thought we had an understanding that social infrastructure is off — they didn’t take any of that off,” said Sen. Shelley Moore Capito (R-W.Va.), the party’s lead negotiator. Republicans similarly had made clear to Biden that they couldn’t support tax increases to pay for the infrastructure package, Capito added, only to have the White House reaffirm its plan to raise rates on corporations when it submitted its latest counteroffer. Days later, the senator said the move left her and her colleagues wondering, “Are you not hearing us?” Asked about the GOP’s characterization of Biden’s position, White House spokesman Andrew Bates said the president would not “negotiate through the press.”
