There is no credible or verifiable evidence from the provided sources or recent authoritative reports to confirm the claim that 129 people, including 36 children, died in Texas and that a Mexican rescue team was told to leave Texas due to permits and protocol but stayed to help.
129 dead in Texas. 36 of them were children. & They just told the Mexican rescue team to leave Texas due to “permits” and “protocol” But they stayed, not for money, not for credit but to help the people in need. This is called leadership! Much respect to these heroes. @GavinNewsom invite them to California and give them the recognition they deserve!

Key Evidence
No credible news reports or official data confirm the death toll of 129 with 36 children in Texas recently. There is also no evidence from reliable sources about a Mexican rescue team being asked to leave Texas due to permits and protocol but choosing to stay to help.
What the Evidence Shows
The claim contains several components: the number of deaths (129 total, 36 children), the involvement of a Mexican rescue team being asked to leave Texas due to permits and protocol, and the assertion that the team stayed voluntarily to help without seeking money or credit. None of the search results or structured sources provide any information related to a recent incident in Texas with these casualty figures or mention a Mexican rescue team being involved or asked to leave.
The sources primarily cover historical and cultural topics related to Mexican-Texan history, cuisine, and demographics, none of which address current events or emergency response situations. Additionally, no official government reports, news articles from established organizations, or credible emergency management sources were found that corroborate these specific details. Without independent verification from reliable news outlets or official statements, this claim remains unsubstantiated.
It is possible that this claim refers to a recent event not yet documented in authoritative sources or is misinformation circulating on social media. Given the lack of evidence and context, the claim cannot be verified at this time.
