Bob Schieffer explains how JFK's assassination shaped his career

Scott Pelley speaks with chief Washington correspondent and anchor of "Face the Nation" Bob Schieffer about the dramatic drop in the approval ratings of Congress and President Obama.

In his series on, CBS sportscaster James Brown interviewed CBS News chief Washington correspondent Bob Schieffer on how President John F. Kennedy's assassination shaped Schieffer's journalism career.

Schieffer started his journalism career as a police reporter at the Fort Worth Star-Telegram in Texas. He said the day Kennedy was assassinated is a day he will never forget.

"The phone rang, and I answered and a woman says is anyone there to give me a ride to Dallas?" Scheiffer said in the series, Conversations with CBS Sports. "And I said 'Well lady, you know, we don't run a taxi service besides the president has been shot.' And she said 'yes, I heard it on the radio I think my son is the one they've arrested.' And it was Lee Harvey Oswald's mother."
