Analysis Summary:

The article's factual accuracy is mostly sound, as it primarily reports on the opinions expressed within a focus group. The bias is moderate, stemming from the selection of participants and the framing of the discussion around specific issues like immigration and family separation, which inherently carry emotional weight. The provided sources offer limited direct verification of the focus group's claims but provide context on related issues.

Detailed Analysis:

• Claim:** Four Arizona voters -- two Republicans, two Democrats -- sat down with CBS News' Ed O'Keefe for a discussion on politics and immigration.
• Verification Source: *Fail to cover*. This is a statement of fact about the setup of the focus group, which the provided sources do not directly confirm or deny.
• Internal Knowledge: This is a standard journalistic practice for political reporting.
• Claim:** The focus group discussed immigration and family separation.
  • Verification Source #1: Supports the general topic of immigration and family separation in Arizona. The title mentions "stark divide on immigration, family separation" in Arizona.
  • Verification Source #3: Supports the general topic of family separation and immigration policy.
• Claim:** (Implicit) The views expressed by the focus group participants are representative of broader political divides in Arizona.
• Verification Source: *Fail to cover*. The provided sources do not assess the representativeness of the focus group. This is a potential source of bias, as a small group may not accurately reflect the views of the entire state.

Supporting Evidence/Contradictions:
