WASHINGTON (AP) — Top Democrats signaled a deal is within reach on President Joe Biden’s big domestic bill but momentum fizzled and tempers flared late Wednesday as a paid family leave proposal fell out and a billionaires’ tax appeared scrapped, mostly to satisfy a pivotal member of the 50-50 Senate.

With his signature domestic initiative at stake, Biden will head to Capitol Hill on Thursday morning to urge Democratic lawmakers to bring talks on the social services and climate change bill “over the finish line” before he departs for global summits overseas.

Still in the mix: expanded health care programs, free pre-kindergarten and some $500 billion to tackle climate change remain in what’s now at least a $1.75 trillion package.

And Democrats are eyeing a new surcharge on the wealthy — 5% on incomes above $10 million and an additional 3% on those beyond $25 million — to help pay for it, according to a person who requested anonymity to discuss the private talks.

“They’re all within our reach. Let’s bring these bills over the finish line.” Biden tweeted late Wednesday.

To help push lawmakers toward that goal, Biden will speak Thursday morning to the House Democratic Caucus, a person familiar with the plan told The Associated Press on condition of anonymity. Besides pressing for important party priorities, the president was hoping to show foreign leaders the U.S. was getting things done under his administration.
