The statement is strongly supported by multiple high-authority primary sources. The core claims of the statement—that a U.S. lawmaker has proposed a ban covering both stocks and cryptocurrencies for government officials—are all confirmed by the evidence.Press releases from the offices of Senator Jon Ossoff and Senator Mark Kelly directly confirm they have introduced legislation, such as the 'Ban Congressional Stock Trading Act,' to prohibit members of Congress from trading stocks. This validates the first part of the statement about a lawmaker proposing a ban.The most crucial part of the claim, the inclusion of cryptocurrencies, is explicitly verified by authoritative sources. A Congressional Research Service (CRS) report on these proposals confirms that the proposed restrictions explicitly include 'digital assets' (cryptocurrencies). Furthermore, the official text of a separate but related bill, S.3555 ('STOCK Act 2.0'), also explicitly includes cryptocurrency in its proposed regulations. The primary legislative texts and the expert analysis from the CRS are in complete agreement.The term "government officials" is appropriate, as the proposals are aimed at Members of Congress, a key group of U.S. government officials. There is no conflicting evidence among the provided sources; they consistently corroborate the existence and substance of these legislative proposals.
