Workflow

Copy this checklist to track progress:

Public Figure Fact-Check Progress:
- [ ] Step 1: Extract verifiable claims
- [ ] Step 2: Search Google Fact Check Tools (MANDATORY)
- [ ] Step 3: Search additional authoritative sources
- [ ] Step 4: Generate structured fact-check report

Step 1: Extract verifiable claims

Identify specific factual statements made by the public figure:

Target claim types:

• •Statistical data and numbers
• •Historical events and dates
• •Scientific or medical statements
• •Financial figures and company data
• •Policy positions and voting records
• •Biographical information

Extract format:

CLAIM: [Exact quote from public figure]
CONTEXT: [When/where it was said]
TYPE: [Statistical/Historical/Scientific/etc.]

Step 2: Search Google Fact Check Tools (MANDATORY)

REQUIRED: Always start with Google Fact Check Tools before other sources

1. •Google Fact Check Explorer: Search for the exact claim or similar statements
2. •Review existing fact-checks: Check if the claim has been previously verified
3. •Analyze ClaimReview data: Look for structured fact-check results
4. •Cross-reference sources: Note which fact-checkers have covered this topic

If Google Fact Check Tools shows existing fact-checks:

• •Review the verdict and methodology
• •Check if the context matches current claim
• •Verify the credibility of the fact-checking organization
• •Use as primary reference point for your analysis

If no existing fact-checks found:

• •Proceed to Step 3 for original verification
• •Note in report that this is a new claim requiring fresh fact-checking

Step 3: Search additional authoritative sources

For each claim, search official and credible sources:

Government data:

• •Official statistics (census.gov, bls.gov, cdc.gov)
• •Government databases and reports
• •Congressional voting records
• •Court documents and legal filings

Academic and research:

• •Peer-reviewed studies
• •University research institutions
• •Scientific journals and publications
• •Medical organizations (WHO, CDC, FDA)

Financial and business:

• •SEC filings and annual reports
• •Financial news from established outlets
• •Company press releases
• •Stock market data

Historical verification:

• •Historical archives and records
• •Newspaper archives
• •Documentary evidence
• •Timeline verification from multiple sources

Step 4: Generate structured fact-check report

Output format for each claim:

Source Evaluation Guidelines

Authoritative Sources (High Priority)

1. •Google Fact Check Tools - MANDATORY first step for all claims
2. •Government agencies - Official statistics, records, databases
3. •Academic institutions - Peer-reviewed research, university studies
4. •Medical organizations - WHO, CDC, FDA, medical journals
5. •Financial regulators - SEC filings, central bank data
6. •News organizations - Established outlets with fact-checking standards
7. •Other fact-checking platforms - Snopes, PolitiFact, FactCheck.org (as secondary verification)

Use with Caution

• •Corporate press releases (may contain bias)
• •Think tank reports (check funding sources)
• •Social media posts (even from experts)
• •Single-source claims

Red Flags

• •No authoritative source available
• •Google Fact Check Tools returns contradictory results
• •Sources contradict each other significantly
• •Only partisan sources support the claim
• •Information is very recent with limited verification

CRITICAL RULE: Never complete a fact-check without consulting Google Fact Check Tools first

Utility Scripts

To automate Google Fact Checker API requests, use the simplified script:

Simple Google Fact Check Query

python scripts/google_fact_checker.py "Senator X said unemployment dropped 40% during his term"

Returns raw string format:

• •Multiple lines for top 5 results: #N: InformationContent
• •NO_RESULTS - if no existing fact-checks
• •ERROR: message - if API error occurred

Example outputs:

#1: Donald Trump was born in the United States | Birth certificate confirms he was born in New York City | Original claim: Trump was born in USA
#2: Official records verify Trump's birthplace as New York | Original claim: Donald Trump birthplace question
#3: Birth certificate authentic and valid | Multiple sources confirm NYC birth
NO_RESULTS
ERROR: API key not found

Examples

Example 1: Political Statistical Claim

User request: "Fact-check: 'Senator X said unemployment dropped 40% during his term'"

Output:

## FACT-CHECK RESULT

### CLAIM #1
**Statement:** "Unemployment dropped 40% during my term in office"
**Source:** Senator X on Twitter, January 8, 2026
**Category:** Statistical

**VERDICT:** ⚠️ MISLEADING

**VERIFICATION:**
- **Google Fact Check Result:** #1: Unemployment claim misleading - shows 2.1 percentage point decrease, not 40% absolute drop | Original claim: Unemployment dropped 40% during term
#2: Economic statistics misrepresented in political statement | Original claim: Similar unemployment claim
- **Primary Source:** Bureau of Labor Statistics unemployment data
- **Supporting Sources:** Federal Reserve economic data, state employment records
- **Date Checked:** January 11, 2026

**ANALYSIS:**
Unemployment did decrease during the senator's term, but only by 2.1 percentage points (from 5.3% to 3.2%), which represents a 40% relative decrease but not an absolute 40% drop.

**CORRECTION:**
**Accurate Statement:** "Unemployment decreased by 2.1 percentage points (a 40% relative reduction) during my term"
**Key Difference:** Original statement implies much larger absolute decrease than actually occurred

Example 2: CEO Business Claim

User request: "Verify: 'Our company's revenue grew 500% last year'"

Output:

## FACT-CHECK RESULT

### CLAIM #1
**Statement:** "Our company's revenue grew 500% last year"
**Source:** CEO Jane Doe at investor conference, January 2026
**Category:** Financial

**VERDICT:** ✅ TRUE

**VERIFICATION:**
- **Google Fact Check Result:** NO_RESULTS
- **Primary Source:** Company's SEC 10-K filing
- **Supporting Sources:** Annual report, audited financial statements
- **Date Checked:** January 11, 2026

**ANALYSIS:**
SEC filings confirm revenue increased from $2M in 2024 to $12M in 2025, representing exactly a 500% increase.

**CORRECTION:** None needed - claim is accurate.
