District of Columbia Sister City Integrity Act

This bill prohibits the District of Columbia government from establishing new sister city relationships with jurisdictions in countries designated as "foreign adversaries" under federal law. It requires the District to terminate any existing sister city relationships with such countries within 180 days of the law's enactment or according to the existing agreement's terms. The District must also certify compliance with this law to receive federal funds for diplomatic liaison and outreach services. The bill directly affects the District's international partnerships and its use of federal funding for diplomatic activities.
