House Democrats, who campaigned on increasing paychecks, have struggled to round up enough votes to pass a bill that would raise the minimum wage to $15 an hour.

In January, lawmakers introduced the Raise the Wage Act, which calls for phasing in an increase to $15 per hour by 2024. Five months later, the measure has cleared a committee vote but languishes on the House floor while Democratic leaders twist the arms of reluctant rank-and-file members whose support is needed to pass the bill.
