This must be confirmed, verified, or established as factual by at least one Source Agency. News confirmation is defined as a published article, broadcast segment, or official news report by a Source Agency, that A) explicitly states <event claim> occurred, is true, or has been verified, B) based on journalistic investigation, sources, or evidence, and C) presented as factual reporting rather than speculation, rumor, or unverified allegation. A pocket veto counts. A veto of a bill or joint resolution passed by the 119th Congress does NOT count, even if made on or after Jan 3, 2027.
