Update: Two veteran lawmakers vie to succeed DeFazio as top T&I panel Democrat.

Transportation and Infrastructure Committee includes the funds in its part of $3.5T reconciliation package.

It's unclear how the new package might mesh with the Biden-Senate bipartisan group framework.

The legislation, which Republicans sharply criticized, is slated for a June 9 committee vote.

Rare example of bipartisan legislation includes about $8.6 billion in federal funds for 34 new Corps projects.

Proposal unveiled by DeFazio is silent on how to pay for the $138-billion trust-fund infusion needed to fully fund it.

State DOT leaders' views vary on whether Congress will pass long-term transport bill by October.
