One of the men injured in Saturday's shooting, 57-year-old David Dutch, was shot in the chest and liver, according to the Marine Corps League of Pennsylvania.

Dutch is no longer in a medically induced coma and has been upgraded from critical to stable condition, the organization said.

Dutch is a former Marine who serves as commandant of his Marine Corps League detachment, the organization said.

The other injured victim, 74-year-old James Copenhaver, has also been upgraded from critical to stable condition, officials said.

In a private phone call with Robert F. Kennedy Jr., former President Donald Trump said the bullet "sounded like the world's largest mosquito."

RFK Jr.'s son posted on X a video of the call, which was filmed from what looks to be RFK Jr.'s hotel room. RFK Jr. had Trump on speaker phone.

The younger Kennedy, Bobby Kennedy III, removed the post after his father said on X that he was "mortified" it became public.

Trump also told RFK Jr. about the phone call he received from President Joe Biden after Saturday's assassination attempt.

"It was very nice, actually. He called me, and he said, 'How did you choose to move to the right?' (Inaudible) Everybody's looking straight on," Trump said. "I said, 'I was just showing a chart.'"

Thomas Matthew Crooks, the 20-year-old suspected gunman, planned to attend Robert Morris University this fall, according to a school spokesperson.

Robert Morris University is a private, four-year university located outside of Pittsburgh.

"We have been in touch with law enforcement and stand ready to assist in their investigation," school spokesperson Brian Edwards said.

Crooks had earned his associate degree in science from a local community college and graduated in May with high honors.

He was accepted into both RMU and the University of Pittsburgh, a public-research university also a close drive from his home in Bethel Park, Pennsylvania.

A spokesperson for the University of Pittsburgh said Crooks was told in February that he could attend this fall semester as a transfer student. In March, Crooks informed Pitt that he would not attend.
