Several of the leading Democrats in Congress who have stood in the way of Joe Biden’s $3.5tn budget package, which includes popular provisions widely expected to help working-class Americans, have taken that stance despite representing districts that have some of the highest rates of poverty and income inequality in the country.

During the month of August, when debate over the budget dominated the headlines, Manchin and Cuellar accepted campaign donations from major corporations whose executives belong to the Business Roundtable and the National Association of Manufacturers, which both oppose the reconciliation package, according to the watchdog group Accountable US.
