Issue salience drives expert report requests by US lawmakers.

New Data & Methods: The study uses privately requested Congressional Research Service reports from 1997 to 2017, rather than public actions. This offers a fresh perspective on how representatives consult experts.

Key Findings: When problems become salient in the public eye, members of Congress increasingly seek expert information—even while managing other priorities or when not introducing major legislation related to that issue.

Real-World Implications: Expert consultations spike during periods when issues are prominent but legislative agendas appear less intense. This suggests a nuanced approach to policy problem-solving.
