The claim is directly reported by a web search result citing The Post, which alleges that radical left-wing groups supporting the ban have shared pro-communist and anti-Israel rhetoric. This specific allegation is presented as a report from an external source, and while the evidence provided does not offer a second independent news source confirming the *rhetoric* aspect, the core allegation structure is repeated in the search results, suggesting corroboration of the *report* itself across multiple search hits.

The claim is directly supported by a web search result stating that 'Far-left Chinatown groups like the “The New York Young Communist League” and “Youth Against Displacement” have campaigned, picketed and petitioned outside of City Hall in support of Lower Manhattan Councilman Chris Marte’s “No More 24” bill.' This constitutes confirmation from the search results.

The web search results corroborate the core elements of the bill's aim: the issue of 24-hour shifts, the payment discrepancy (paid for 13 hours), and the general effort to stop the practice. One source mentions the requirement for rest, and another details the payment issue, confirming the substance of the claim.

The web search results confirm the existence and nature of the New York Young Communist League (NYYCL) as a youth wing of the CPUSA. While the evidence does not explicitly confirm the 'training ground' claim or the positive messaging about Stalin/Mao/China, the search results confirm the group's existence and ideological nature, which supports the context of the claim.
