WASHINGTON (AP) — A bipartisan group of senators is eyeing an infrastructure deal with $579 billion in new spending as of a $1 trillion package. That’s according to people briefed on the plan. It could be rolled out as soon as Thursday. Negotiators are trying to strike a deal on President Joe Biden’s top priority. The 10 senators have been huddling behind closed doors, encouraged by Biden to keep working on the effort after he walked away from a Republican-only proposal this week unable to resolve differences. The senators cautioned changes could still be made.
