Protecting Jobs and Wages from Regulations Act of 2020 This bill revises and expands the requirements for federal agency rulemaking by requiring agencies, in making a rule, to base all preliminary and final factual determinations on evidence and to consider the legal authority under which the rule may be proposed, the specific nature and significance of the problem the agency may address with the rule, any reasonable alternatives for the rule, and the potential costs and benefits associated with such alternatives.
