NEW YORK — President Barack Obama's candid thoughts about Kanye West are provoking a debate over standards of journalism in the Twitter age. ABC News says it was wrong for its employees to tweet that Obama had called West a "jackass" for the rapper's treatment of country singer Taylor Swift. The network said some of its employees had overheard a conversation between the president and CNBC's John Harwood and didn't realize it was considered off the record. The network apologized to the White House and CNBC.
