Plans called for an around-the-clock fire watch of advocates at the Capitol to last until Monday afternoon, when the Senate is again scheduled to vote on the Promise to Address Comprehensive Toxics Act, better known as the PACT Act. The goal was to emphasize — throughout the weekend — the importance of action on the issue, even if no lawmakers were present to see it.

The upper chamber must pass the measure again, as the House version of the bill includes technical changes from the measure passed last month. The bill then heads to President Biden’s desk, where he is expected to sign it.
