The Note: Keeping An Eye On Chris Christie
--CHRISTIE POLITICAL ALLY TO PLEAD GUILTY IN BRIDGE PROBE: A key figure in the corruption scandal that threatens New Jersey Gov. Chris Christie's political career is poised to plead guilty in federal court today, sources told ABC's JOSH MARGOLIN.

The Note: What's Worrying Bernie Sanders?
--BERNIE SANDERS MAKES IT OFFICIAL -- 'I AM RUNNING FOR PRESIDENT': Sen. Bernie Sanders, I-Vermont, is running for president in 2016, Sanders said in an interview with ABC's JONATHAN KARL. "I am running for president," Sanders said. "I intend to stand up and fight for working families all over the country." Sanders, who is the longest-serving independent in congressional history, said he will run for president as a Democrat. Sanders will hold a formal kick-off event in May, most likely in his home state of Vermont. Sanders' entry in the race gives Democrats at least one liberal alternative to former Secretary of State Hillary Clinton, who declared her candidacy earlier this month. Sanders will also be Clinton's first formal Democratic challenger, ABC's RICK KLEIN and ARLETTE SAENZ note. http://abcn.ws/1zlkKaz WATCH KARL's interview with Sanders on "Good Morning America": http://abcn.ws/1P9VN3u
