WASHINGTON — President Joe Biden will announce Thursday that he has reached a deal with Senate Democratic holdouts on a social spending and climate bill, according to multiple sources with knowledge of his plans.

The apparent deal represents the culmination of months of sometimes tense negotiations between moderate and progressive lawmakers.

Biden will travel to Capitol Hill on Thursday morning to attend a meeting of the House Democratic caucus. There, he is expected to appeal to House progressives to vote for the stalled $1 trillion infrastructure bill, which has already passed the Senate.

It was unclear Thursday whether progressives would agree to rally behind the infrastructure bill, which does not contain many of their top priorities. Progressives so far have refused to back the infrastructure bill, demanding that Democratic leaders first release firm legislative language for the companion social spending bill.

Following the House meeting, Biden will deliver remarks on the framework at 11:30 am ET, before departing for a week of summits in Europe.
