特朗普总统签署行政令限制机构收购独栋住宅

The evidence provided strongly supports the truthfulness of the statement. The most authoritative sources are direct communications from the White House: a presidential action and an accompanying fact sheet. These primary sources explicitly state the administration's policy and action to stop large institutional investors from purchasing single-family homes. This is corroborated by multiple, highly credible news outlets, including Reuters and CNBC, which report directly that President Trump signed the executive order. While some sources discuss the policy as a proposal or an intention, these were published prior to the executive action or provide broader context, and they do not contradict the sources confirming the action was taken. There is no conflicting evidence among the provided sources. The consistency across primary government sources and secondary journalistic reports provides a high degree of confidence in the statement's accuracy.
