F.B.I. officials, speaking on a conference call with members of Congress, said that that the gunman's search history on his electronic devices included images of public figures — including Trump and Biden — along with dates of Trump appearances and the Democratic National Convention in Chicago, according to a person who was on the call.
The person on the call singled out some of the searches on one of the gunman's cellphones — the device he left in his residence — saying that he had looked up "major depressive disorder."
