NEW ORLEANS - A conservative activist accused of trying to tamper with Democratic Sen.

NEW ORLEANS - Investigators pressed ahead with their probe of four men accused of trying to tamper with a senator's phones after a lawyer said the conservative activists were just trying to capture embarrassing video of her staff ignoring constituent calls.

NEW ORLEANS - Louisiana Sen. Mary Landrieu says allegations that a conservative activist and three other men tried to tamper with phones at her New Orleans office are "unsettling." One of the suspects is James O'Keefe, a conservative activist who posed as a pimp last year on hidden camera to target the liberal community-organizing group ACORN.
