Analysis Summary:

The article's factual accuracy is mixed due to the lack of specific details about the removal of Mike Waltz and the reasons cited by H.R. McMaster. Without external verification sources, it's difficult to assess the validity of the claim that Waltz's removal is "significant" for U.S. national security. The article presents McMaster's opinion, which inherently introduces a degree of bias, although it's presented as his professional assessment.

Detailed Analysis:

• Claim 1:** "Retired Lt. Gen. H.R. McMaster, a CBS News contributor who served as national security adviser in President Trump's first term, tells 'Face the Nation with Margaret Brennan' that this week's removal of Mike Waltz as national security adviser will be 'significant' for U.S. national security interests."
• This claim is partially verifiable through internal knowledge. H.R. McMaster did serve as National Security Advisor under Trump, and CBS News is a legitimate news outlet. However, the core of the claim - the "removal of Mike Waltz as national security adviser" - is problematic. Mike Waltz is a U.S. Representative, not a national security advisor. This suggests a potential error in the reporting or a misstatement by McMaster that the article doesn't clarify. *Fail to cover* (due to the apparent error).
• Claim 2:** (Implied) Mike Waltz held a national security advisor position.
• This is factually incorrect based on internal knowledge. Mike Waltz is a U.S. Representative. This contradicts the implied claim.

Supporting Evidence/Contradictions:

• Internal Knowledge: Contradicts the claim that Mike Waltz was a national security advisor. He is a U.S. Representative.
• Lack of Verification Sources: The absence of external sources prevents a thorough assessment of the context and accuracy of McMaster's statement.
