Comment on US announces new efforts to reduce methane emissions

TikTok and its Chinese parent company ByteDance are suing the U. S. over a law that would ban the popular video-sharing app unless it’s sold to another company. The lawsuit filed on Tuesday may be setting up what could be a protracted legal fight over TikTok’s future in the United States. The popular social video company alleged the law, which President Joe Biden signed as part of a larger $95 billion foreign aid package, is so “obviously unconstitutional” that the sponsors of The Protecting Americans From Foreign Adversary Controlled Applications Act are trying to portray the law not as a ban, but as a regulation of TikTok’s ownership. [time-brightcove not-tgx=”true”] “Congress has taken the unprecedented step of expressly singling out and banning TikTok: a vibrant online forum for protected speech and expression used by 170 million Americans to create, share, and view videos over the Internet,” ByteDance said in its suit.
