Analysis Summary:

The CBS News article is mostly accurate, reporting on the widespread heat advisories and record high temperatures across the US. The claim about 128 million Americans under heat advisories is supported by a similar claim in Verification Source #1. The article appears to be generally objective, with minimal discernible bias.

Detailed Analysis:

• Claim:** About 128 million Americans from Louisiana to Maine are still under heat advisories.
  • Verification Source #1: States "nearly half the nation's population was under a heat advisory or excessive heat warning." While not exactly 128 million, this supports the claim of a widespread heat advisory affecting a large portion of the US population.
• Claim:** Dozens of record high temperatures were set Tuesday in parts of the U.S.
  • Verification Source #3: States "A relentless heat wave continued to bake most of the United States on Friday, with numerous areas expected to see record-breaking temperatures." This supports the claim of record-breaking temperatures in parts of the US.
• Claim:** CBS News' Rob Marciano reports.
• This is a statement about the source of the report and cannot be verified by the provided sources.

Supporting Evidence/Contradictions:

• Verification Source #1: Supports the claim of widespread heat advisories.
• Verification Source #3: Supports the claim of record-breaking temperatures.
• Verification Source #4: Provides a specific example of record temperatures in Central Park, NYC, further supporting the general claim of record heat.
• Verification Source #5: Mentions excessive heat warnings in California, further supporting the widespread nature of the heatwave.
• Verification Source #2: While about heatwaves, it is in South America (Chile), and therefore not directly relevant to the US heatwave.
