Shanda Maloney was awake last night when she saw news reports about the shooting. She jumped in her car and started giving rides to anyone who needed them.
"Hearing all the sirens around, you feel completely helpless," she tells CNN. "I just started tweeting if you need a ride [I'll come pick you up]."
After that, she drove to United Blood Bank Services at 4:30 a.m. to donate blood — and found many others already waiting in line.
She said she's still in line and won't leave the blood bank until she can donate.
According to Las Vegas Sheriff Joseph Lombardo, police found at least 10 rifles in Stephen Paddock's room at the Mandalay Bay Hotel.
White House press secretary Sarah Sanders said President Trump will speak about the shooting sometime this morning.
"We are tracking for the President to make remarks this morning. Will keep you all updated as details are finalized," Sanders said.
Asked if police were classifying this shooting as a terror attack, Las Vegas Sheriff Joseph Lombardo said, "We have to establish what his motivation was first."
“There’s motivating factors associated with terrorism other than a distraught person just intending to cause mass casualties," he said. "Before we label with that, it'll be a matter of process."
