CBS News reported that Democratic Rep. Haley Stevens shocked her party this weekend by endorsing Republican Mike Rogers for Senate over her primary opponent, Abdul El-Sayed. The network's video report on the endorsement is the source for the details in this story.

Curtis Hertel Jr., the state's Democratic Party chair, joined The Daily Report to discuss the endorsement, according to CBS News. The network reported that Hertel said Stevens "lied to her own constituents." The report's headline uses the same words.

CBS News identified Hertel as the chair of the Michigan Democratic Party and described his appearance as a discussion of the endorsement. The network's summary does not describe the questions asked during the segment or any further statements made in it.

The summary does not say which constituents Hertel meant or what evidence, if any, he cited for his claim. It also does not say what reasons Stevens gave for backing Rogers over El-Sayed in the Senate contest.

The summary does not include a response from Stevens, Rogers, or El-Sayed to Hertel's remarks. It also does not describe reactions from other Michigan Democrats or from voters, and it does not say whether party leaders have taken any action regarding the endorsement.

CBS News describes Stevens as a Democratic representative and Rogers as a Republican, and it identifies El-Sayed as Stevens's primary opponent. Beyond those descriptions and Hertel's remark, the summary offers no further detail about the endorsement or the dispute.

The details in this story come from the title and summary CBS News published for its video. The full segment may contain additional information that is not reflected in those materials.
