Sen. Bob Menendez may seek exoneration at his May bribery trial by blaming his wife, saying she kept him in the dark about anything that could be illegal about her dealings with New Jersey businessmen, according to court papers unsealed Tuesday. Several sentences in a January court filing by lawyers for the Democrat were unsealed in Manhattan federal court after some news organizations insisted that public disclosure was required. Menendez’s lawyers had redacted the documents, claiming that the sentences revealed trial strategy that could bias the jury pool.
