Former President Donald Trump was still revising his speech less than an hour before his scheduled remarks at 8:15 p.m. ET, sources said.
Sources said he spent the entire flight to Florida working on his speech. While his remarks are expected to be in a teleprompter, aides are preparing for him to go off script.
Sources described Trump's mood as "determined, resolute and up for the challenge," though that he was also "angry" leaving court this afternoon.
