Obama announces Hagel's resignation

WASHINGTON (Reuters) - President Barack Obama accepted Defense Secretary Chuck Hagel's resignation on Monday, saying Hagel had approached him last month to say it was time for him to leave. At a White House event in the State Dining Room, Obama and Vice President Joe Biden gave Hagel a warm sendoff. He said Hagel will stay on until a successor is confirmed by the Senate. He said Hagel has been candid with his advice and counsel and has "always given it to me straight." (Reporting By Steve Holland; Editing by Doina Chiacu)
