Just one day before President John F. Kennedy’s life was cut short, thousands are gathering in Dallas to reflect on the 50th anniversary of his assassination.

In Thursday’s Capital Tonight, we reported live from Dallas as the city prepares to remember a moment that changed history and the man whose life was cut short.

AFTER THE OATH

Hours after the bullets struck, a new president was sworn in on Air Force One at Dallas Love Field. We spoke to Mark Updegrove of the LBJ presidential library about how Lyndon B. Johnson handled the transition from tragedy.

WITNESS TO HISTORY

And millions of Americans remember where they were when they heard the news, but one man had to be among of the first to tell them. Click on the image below to see radio broadcaster Gary DeLaune tell his story.
