Gov. Tim Walz and Democratic legislative leaders are blaming House Republicans for the failure of the Legislature to agree on a public construction borrowing bill before time ran out on the 2020 regular session. But they said Monday they’ll keep trying to reach a deal in time for a special session that’s expected to begin June 12. The bonding bill was the most important piece of legislation that needed approval before Sunday night’s deadline. But bonding bills require three-fifths majorities and bipartisan support, which never came together in a session that was upended by the COVID-19 pandemic.
