The attorneys general in California and Nevada are partnering in investigations into the mortgage meltdown that crippled both states.
California Attorney General Kamala Harris and her Nevada counterpart Catherine Cortez Masto said Tuesday they will combine resources and share information about mortgage fraud probes each have launched.
Nevada has the nation's highest foreclosure rate while California ranks second.
Harris recently subpoenaed mortgage giants Fannie Mae and Freddie Mac, looking into lending practices.
Masto has indicted two Southern California title officers for allegedly running a so-called "robo-signing" scheme to sign and file thousands of fraudulent foreclosure documents in Las Vegas.
Harris announced in September that California would not agree to a planned 50-state settlement over foreclosure abuses that federal officials and other state attorneys general are negotiating with major U.S. banks.
