Generally, contributions from individuals, corporations, unions and other organizations are permitted.  Federal election law prohibits political committees in this country from receiving contributions from foreign nationals (individuals, corporations or other foreign business entities), national banks and corporations organized by authority of Congress and federal government contractors. Political committees supporting candidates subject to contribution limits have special contributor restrictions.  There are also restrictions in place for committees contributing to other political committees.  Local restrictions may apply to political committees supporting candidates seeking some county and city offices. Check with your county auditor (King County: Records, Elections and Licensing Services Division) or your city clerk.
