Trump Jr. says father is 'changed man'

The man suspected of shooting Donald Trump previously sought to join his high school's rifle club, but was rejected and asked not to return, two students who were members of the team at the time told ABC News.

The suspect, Thomas Crooks, attended what was described as "preseason" for the rifle club, which is held before tryouts, but he did not make it to the tryouts, the two team members said. Both students said Crooks was a "bad shot," with one adding that he wasn't the right "fit."

"He didn't just not make the team -- he was asked not to come back because how bad of a shot he was. It was considered like, dangerous," classmate Jameson Myers told ABC News.

"On the first day of preseason, he basically couldn't even hit the target," Myers said.

The team's coach declined to comment and referred questions to the school district. A spokesman for the school district did not immediately respond to a request for comment.

The two people injured in Saturday's shooting have been upgraded from critical condition to stable condition, according to the Pennsylvania State Police.

Police identified 57-year-old David Dutch, of New Kensington, Pennsylvania, and 74-year-old James Copenhaver, of Moon Township, Pennsylvania, as the injured shooting victims.

The two people who were critically wounded in the assassination attempt on former President Donald Trump have been identified.

Killed in the shooting was Corey Comperatore, 50, of Sarver, Pennsylvania.

Pennsylvania Gov. Josh Shapiro has ordered flags to be flown at half-staff in honor of Comperatore, a firefighter who leaves behind a wife and two daughters.

The U.S. Secret Service is investigating how a gunman armed with an AR-style rifle was able to get close enough to shoot and injure former President Donald Trump at a rally Saturday in Pennsylvania, a monumental failure of one of the agency's core duties.

The gunman, who was killed by Secret Service personnel, fired multiple shots at the stage from an "elevated position outside of the rally venue," the agency said.

Former President Donald Trump said he will head to Milwaukee for the Republican National Convention on Sunday afternoon.

Trump wrote on social media that he was going to delay the trip by two days, "but have just decided that I cannot allow a 'shooter,' or potential assassin, to force change to scheduling, or anything else."
