(Portland, OR) -- Republican members of Congress on the Judiciary Committee are asking Oregon law enforcement officials for answers about federal immigration enforcement. They want to know why Oregon officials aren't cooperating with federal immigration authorities. Multnomah County District Attorney Nathan Vasquez responded that under state law, his responsibility is to enforce state criminal laws, not federal immigration laws. The committee is giving them until July 7th to provide a long list of documents showing communications with Immigration and Customs Enforcement.
