Legitimization or Delegitimization? A Multimodal Critical Discourse Analysis of the 2025 Los Angeles Protests in CNN and Fox News

In the context of polarized media discourse, this study examines how outlets with distinct political leanings constructed multimodal representations of the 2025 Los Angeles protests. Adopting a corpus-assisted Multimodal Critical Discourse Analysis (MCDA) framework, this study integrates Entman’s framing theory with Kress and van Leeuwen’s visual grammar to analyze news coverage of the protests. The results reveal a divergence in multimodal strategies. Fox News employs a delegitimization frame through a dominant strategy of reinforcement, where images serve as direct evidence for textual claims. Conversely, CNN constructs a conditional legitimacy frame via a more nuanced strategy, through which the outlet strategically utilizes multimodal contradiction to negotiate with the “protest paradigm” and mitigate the visual reality of disorder. The findings demonstrate how partisan media leverage distinct multimodal strategies to reconstruct opposing social realities. The study contributes to political discourse research by going beyond textual bias to reveal how multimodal strategies function in media polarization environments.
