 Former President Trump is said to be doing fine after what the FBI says was an assassination attempt at a rally Saturday in Butler, Pennsylvania. Police say 20-year-old shooter Thomas Crooks of Bethel Park, Pennsylvania, fired several shots at the rally, one bullet grazing Trump's right ear. One rally-goer was killed, two others critically injured. And as Lisa Taylor reports for us this morning, witnesses told police the shooter had been moving from roof to roof before the shooting.
