TRENTON, N.J. (AP) — New Jersey Gov. Chris Christie says he disagrees with President Obama's decision to normalize relations with Cuba and wants the president to demand the return of a convicted cop killer before diplomatic relations proceed. Christie outlined his requests in a letter sent to the White House last week and released by his office Sunday. Joanne Chesimard was convicted of killing a New Jersey state trooper in 1973 but escaped from prison and fled to Cuba, where she was granted asylum. A spokeswoman for the White House's National Security Council says it will continue to press the Cuban government to return U.S.
