Analysis Summary:

The CBS World article contains inaccuracies regarding the timeline and outcome of the impeachment process. While it correctly identifies Yoon Suk Yeol as the impeached president, it incorrectly states he was removed from office four months after declaring martial law. The provided sources indicate a more complex and initially unsuccessful impeachment process. There's a moderate bias due to the simplified and somewhat misleading presentation of events.

Detailed Analysis:

• Claim 1:** "Impeached President Yoon Suk Yeol was removed from office four months after he declared martial law, sending troops into parliament."
• Verification Source #1: Supports the removal of Yoon Suk Yeol from office.
• Verification Source #2: Supports the initial impeachment of Yoon Suk Yeol.
• Verification Source #3: Supports the declaration of martial law.
• Verification Source #4: Supports the declaration of martial law and subsequent backing down.
• Verification Source #5: Contradicts the claim that he was removed four months after declaring martial law, as it states he *survived* an initial impeachment vote.
• Analysis: The claim is partially accurate but misleading. While Yoon Suk Yeol was eventually removed, the timeline and initial survival of the impeachment vote are not reflected, making the statement inaccurate. The claim about sending troops into parliament is not explicitly covered in the provided sources, but the declaration of martial law implies military involvement.

Supporting Evidence/Contradictions:

• Verification Source #1: "The country’s Constitutional Court formally ended the presidency of Yoon Suk Yeol for declaring martial law, ending months of turmoil." This supports the removal from office.
• Verification Source #2: "South Korea’s President Is Impeached After Martial Law Crisis." This supports the initial impeachment.
• Verification Source #5: "South Korea’s Leader Survives Impeachment Vote After His Power Grab." This directly contradicts the claim that he was removed four months after declaring martial law, as it shows he initially survived an impeachment vote.
• Verification Source #4: "Soon after President Yoon Suk Yeol’s declaration on Tuesday, lawmakers voted to defy him, prompting the president to say he was lifting his order." This shows the martial law declaration was short-lived.
