During President Trump's early presidency, intense media coverage about political scandals raised questions: do these stories impact partisan opinions or just highlight issues to partisans? This study uses a unique experimental approach—randomly exposing participants to varying levels of Trump-Russia scandal headlines over one week in June 2017—to address limitations in past research. Unlike previous studies that relied on self-reported media use and single exposures, this design provides multiple contacts with the same information.

Experimental Design:

• Used a repeated exposure setup spanning one week

• Randomly assigned participants to view more or fewer headlines

• Mimicked sustained news focus in an environment of high media choice

Key Findings:

• Republicans exposed to more scandal headlines rated Trump's performance lower and expressed stronger negative emotions toward him.

• Democrats and Independents showed no significant change in opinion based on exposure level.

• Perception of media bias remained consistent across participants regardless of headline exposure.

Implications:

These results suggest that even brief, repeated exposures to negative political coverage can influence partisan evaluations by shaping their perception of the information landscape.
